Note that, since poll answers belong to a user and not to a voter, we aren't doing anything regarding poll answers. This is a separate topic that might be dealt with in a separate pull request. Also note that, since there are no records belonging to poll voters, and poll voters don't use `acts_as_paranoia` and don't have any callbacks on destroy, it doesn't really matter whether we call `destroy!` or `delete`. We're using `delete` so there are no unintended side-effects that might affect voters with the same `user_id` and `poll_id` on Consul Democracy installations customizing this behavior.
