Rewrite the loop "break unless a = order.next! while !order.delivery?" to correct the offenses. Not adding a helper because the change was only needed in a couple of places.
The `login_as_admin_and_visit` helper was used a lot but isn't really
shorter than:
login_as_admin
visit path_visit
Calling those methods separately reduces line length. It also removes
the potential impression that it may be more efficient to use the
helper. Now we have less indirection if one of the calls fails and see
the failing spec line straight away.
