Since IRB has improved its support for multiline, the main argument
towars using a trailing dot no longer affects most people.
It still affects me, though, since I use Pry :), but I agree
leading dots are more readable, so I'm enabling the rule anyway.
Not doing so has a few gotchas when working with relations, particularly
with records which are not stored in the database.
I'm excluding the related content file because it's got a very peculiar
relationship with itself: the `has_one :opposite_related_content` has no
inverse; the relation itself is its inverse. It's a false positive since
the inverse condition is true:
```
content.opposite_related_content.opposite_related_content.object_id ==
content.object_id
```
Just like we do in the Budget module, and in some places in the Poll and
Legislation modules, we don't need to specify the class name when the
name of the relation matches the name of a class in the same module.
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.

Avoid to raise an exception `Module::DelegationError' when trying to
show the name and/or email of a poll officer whose user account has
been deleted.
We'll show a message "User deleted" and "Email deleted" instead.
This way we can easily add a test which will fail if by accident we
change the method to use `Date.today`. Until now using `Date.today`
would only fail if we ran specs in a time zone with a different date.
