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.

The restore feature was not working properly. When pushed, the button
was removing the notification from the admins panel, but it was not
restoring in the proposal.
I added an `after_restore` function (that I missed in the first PR)
so that the notification is unmarked as moderated.
Add new routes for the proposal notifications edition and
abilities to let moderators edit it (mark as ignored, hide, etc.).
The notifications are not flaggable because they doesn't work like that,
but in a similar way. The moderator/administrator is in charge of hidding
them through the UI, so the normal users don't flag it as inappropriate.
New controller Moderation::ProposalNotification to manage the moderators
work.
