We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.

Settings are stored in the database, and so any changes to the settings
done during the tests are automatically rolled back between one test and
the next one.
There were also a few places where we weren't using an `after` block but
changing the setting at the end of the test.
- Create concern to reuse the logic of detection of non-existent
translations in Controllers.
- Add detect_remote_translation method:
* This method will be called from controllers to recover resources
without translation.
* Receive arrays of resources.
* Return an array with hashes of remote_translations values for
every resources that have not translations.
* This array will be the param that will be sent from view to
RemoteTranslationController for create remote translations instances.
