Add missing dots.
Improve formatting.
Following up on #33747, this takes things a step further by pulling out
the method name from the arguments array, letting us skip an allocation
in the case where there are no arguments -- notably, this also no longer
*requires* the splat to be an array, allowing us to benefit from
optimizations in Jruby (and maybe MRI in the future) of skipping the
array allocation entirely.

The multiplication of the value takes a long time when we can instead mutate and use the string value directly.
The `microsec` perf increases speed by 27% in the ideal case (which is the most common).
```
original_string = ".443959"

x.report("multiply") {
string = original_string.dup
(string.to_r * 1_000_000).to_i

string = original_string.dup
if string && string.start_with?(".".freeze) && string.length == 7
string[0] = ''.freeze
string.to_i
end

Instead of using a splat on the head and tail we can mutate the array by flattening 1 level. We get further savings by not allocating another via `compact` but instead by using `compact!`
We originally did the whole `load_database_yaml` thing because this test
wasn't cooperating and we needed to finish the namespaced rake tasks for
multiple databases.
However, it turns out that YAML can't eval ERB if you don't tell it it's
ERB so you get Pysch parse errors if you're using multi-line ERB or
ERB with conditionals. It's a hot mess.
After trying a few things and thinking it over we decided that it wasn't
worth bandaiding over, the test needed to be improved. The test was
added in #31135 to test that the env is loaded in these tasks. But it
was blowing up because we were trying to read a database name out of the
configuration - however that's not the purpose of this change. We want
to read environment files in the rake tasks, but not in the config
file.
In this PR we changed the test to test what the PR was actually fixing.
We've also deleted the `load_database_yaml` because it caused more
problems than it was worth. This should fix the issues described in
https://github.com/rails/rails/pull/32274#issuecomment-384161057. We
also had these problems at GitHub.

Issue #27852 reports that when `rails db:create` fails, it causes
leaking of user's DB credentials to $stderr.
We print a DB's configuration hash in order to help users more quickly
to figure out what could be wrong with his configuration.
This commit changes message from
"Couldn't create database for #{configuration.inspect}" to
"Couldn't create '#{configuration['database']}' database. Please check your configuration.".
There are two PRs that fixing it #27878, #27879, but they need a bit more work.
I decided help to finish this and added Author of those PRs credit in this commit.
Since it is a security issue, I think we should backport it to
`5-2-stable`, and `5-1-stable`.

This commit adds a skeleton of "Ruby on Rails 6.0 Release Notes".
It isn't a good time to add changelogs' entries to this guide since we can
redo/revert some things till the final release 6.0.
It would be better to do it close to the release.
But we already can add mentions about major features
that have been added to 6.0. I added mention about "Parallel Testing".
In the system test template, enter a value based on label.
However, since `label` method does not use `titleize` by default.
If generate a value including underscore, cannot find a label and the test
will fail.
```
$ ./bin/rails g scaffold user name:string phone_number:string
$ ./bin/rails t test/system/users_test.rb
E
Error:
UsersTest#test_creating_a_User:
Capybara::ElementNotFound: Unable to find field "Phone Number"
test/system/users_test.rb:18:in `block in <class:UsersTest>'
```
This removes unnecessary `titleize` so that the generated file will pass
even if the attribute contains an underscore.
* Update the comments for TimeWithZone subtraction
While reading the description/documentation comments for the subtraction method, it was confusing. While in practical usage, the returned values make sense. It seems as though the explanation could be a bit clearer.
* Removed erroneous closing parenthesis

`changes_applied` should be called before continuing around callback
chain. Otherwise the mutation tracker returns old value for methods like
`changed`? or `id_in_database` in around callbacks. Also methods depend
on `id_in_database`, like `update_column`, are not working in
`around_create` callbacks.
```
class Foo < ActiveRecord::Base
around_create :around_create_callback
def around_create_callback
...
yield
p id_in_database # => nil
update_column(:generated_column, generate_value) # silently fails
end
...
end
```
* Call block to #redirect_to in controller context
The documentation for ActionController::Redirecting states that a Proc
argument "will be executed in the controller's context." However,
unless #instance_eval is used (removed in 6b3ad0ca), that statement is
false for procs defined outside of the controller instance.
This commit restores the documented behavior.
Fixes#33731.
* Move test proc into a constant in another class
Per @rafaelfranca's suggestion.

* Add documentation for `:collation` option
The table definition supports a `:collation` option for string and text columns, but this is not documented anywhere that I could find.
I'm not sure if the "If not specified" part is accurate. From [this PR](1515c4d98d), it looks like it passes `nil` and lets the database handle the collation, but I'm happy to change it if I misread the code.

* FIX remove whitespace

Previously ActiveRecord couldn't find inverse associations if they were plural, which is a pretty standard use case. This commit changes the behavior to first attempt to find the singular version, then attempt to find the plural version. That makes it work and find plural associations as in the example below:
```
class Post
has_many :comments
end
class Comment
belongs_to :post
end
```
Previously the `:post` association reflection would only attempt to find a `comment` inverse, as opposed to both a `comment` and `comments` inverse.
This commit is the next work after #33523.
Also, this commit removes mention about hidden `utf8` input. Since
form helpers don't generate this input by default since #32125.
Note that I also had created PR #31972 with improvements to
"Action View Form Helpers" guide, but I'll rebase it after merging the
current PR.
