`I18n.translate` helper will wrap the missing translation keys
in a <span> tag only if `debug_missing_translation` configuration has
a truthy value. Default value is `true`. For example in `application.rb`:
# in order to turn off missing key wrapping
config.action_view.debug_missing_translation = false
This test needs to have a require for the Listen gem or else it returns
an error when run by itself or with a certain order in the Active
Support tests. We use `silence_warnings` because Listen has some
warnings about private methods. It's already silenced when it's required
in Active Support EventedFileUpdateChecker.
```
1) Error:
