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.

Having exceptions is better than having silent bugs.
There are a few methods I've kept the same way they were.
The `RelatedContentScore#score_with_opposite` method is a bit peculiar:
it creates scores for both itself and the opposite related content,
which means the opposite related content will try to create the same
scores as well.
We've already got a test to check `Budget::Ballot#add_investment` when
creating a line fails ("Edge case voting a non-elegible investment").
Finally, the method `User#send_oauth_confirmation_instructions` doesn't
update the record when the email address isn't already present, leading
to the test "Try to register with the email of an already existing user,
when an unconfirmed email was provided by oauth" fo fail if we raise an
exception for an invalid user. That's because updating a user's email
doesn't update the database automatically, but instead a confirmation
email is sent.
There are also a few false positives for classes which don't have bang
methods (like the GraphQL classes) or destroying attachments.
For these reasons, I'm adding the rule with a "Refactor" severity,
meaning it's a rule we can break if necessary.
Before we disabled featured proposals by default, there were many tests
creating them because they were needed in order to create non-featured
proposals.
But now these tests don't need to create featured proposals anymore.
The `type: :feature` is automatically detected by RSpec because these
tests are inside the `spec/features` folder. Using `feature` re-adds a
`type: :feature` to these files, which will result in a conflict when we
upgrade to Rails 5.1's system tests.
Because of this change, we also need to change `background` to `before`
or else these tests will fail.
As pointed out in PR #2734:
"After clicking the first link, there's an AJAX request which replaces
the existing `.in-favor a` and `.against a` links with new elements. So
if Capybara tries to click the existing `.against a` link at the same
moment it's being replaced, clicking the link won't generate a new
request".
Making Capybara check the page for new content before clicking the
second link solves the problem, in the same way 4ddc869 solved the same
problem in the comments section.
* Some backgrounds created variables which were never used (@debates).
This made the tests fail when the debate orders changed.
* Some backgrounds visited pages when they didn’t need to
* Pablo and Manuela are now created at the beginning
