Use beaneater 1.0.0 to workardound ArgumentError: wrong number of arguments error

This commit addresses Rails CI `ArgumentError: wrong number of arguments (given 2, expected 1)`
errors at https://buildkite.com/rails/rails/builds/76966#8aea460d-a196-4a38-a7dc-b41af5187d9a/1485-1518
by locking `beaneater` version to 1.0.0. Because `backburner` gem depends on `beaneater`.
and `beaneater` 1.1.0 has been released which triggers this error.

- Errors are reported at Rails CI
https://buildkite.com/rails/rails/builds/76966#8aea460d-a196-4a38-a7dc-b41af5187d9a/1485-1518

- Steps to reproduce
```
git clone https://github.com/rails/rails
cd rails
rm Gemfile.lock
bundle install
cd activejob
bundle exec rake test:integration:backburner
```

- Expected behavior
It should pass

- Actual behavior
ArgumentError: wrong number of arguments (given 2, expected 1)

This workaround can be removed newer versions of `beaneater` released
including this pull request or similar fix.
