Since version 2.0 introduced many breaking changes, we're upgrading to
it first.
The changes have been done by installing the rubocop-faker gem and
running:
```
rubocop \
--require rubocop-faker \
--only Faker/DeprecatedArguments \
--auto-correct
```
The method `available_locales` in
`RemoteTranslations::Microsoft::AvailableLocales` needs to execute a
request to an external server in order to work, meaning it will fail if
the machine its executed on doesn't have an internet connection.
So we're stubbing the method in the tests using it.
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.
