We were inconsistent on this one. I consider it particularly useful when
a method starts with a `return` statement.
In other cases, we probably shouldn't have a guard rule in the middle of
a method in any case, but that's a different refactoring.
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.
To make it more consistent with the rest of the Admin panel,
the CRUD for budget groups and headings has been changed
from the old "all-in-one" form to a separate form for each resource.
Before Budget.current could return multiple budgets, now there can only
be a single current_budget.
Adding the concept of open, which better reflects what the admin sees
in this page: A tab for open budgets and a tab for finished budgets
Why:
* As seen on preproduction and production environments on Madrid's fork. Budget::Result#calculate_winners is very costly when done to all headings for a given budget (as requested on Admin::BudgetsController#calculate_winners) but its not when done individually for only a heading (as requested on Budget::Investment#recalculate_heading_winners)
How:
* Removing `handle_asynchronously :calculate_winners` from bellow Budget::Result#calculate_winners definition, to avoid making any call delayed. And explicitly calling `.delay` only when needed (on Admin::BudgetsController#calculate_winners)
