Since the change on commit cbbe188d6 we added a Poll.current.any?
condition to show the officing link on admin menu to officers.
That condition doesn't have much sense since Poll results only can be
added after a poll has ended, and there may be only one active poll.
We're trying to be consistent; in the past, we had the partials
"shared/admin_login_items", "layouts/notification_item" and
"devise/menu/login_items". Now we're moving all these partials to
components in the `Layout` namespace.
