This happened when `current_user` didn't have a locale stored in the
database and the `current_locale` method returned the default locale.
And the test "Poll Votation Type Multiple answers" would indeed fail if
we removed the `reload` method. However, we can remove the need to
reload the record by avoiding the mentioned changes on the current user
record.
So we're changing the `User#locale` method so it doesn't modify the user
record.
