We added the ability here to check if a role has a user in with the ability to refresh the role cache before checking.  Since some tests will make inline requests, which in turn put a user into a new role, we have to refresh afterwards otherwise we won't see that new role in place.  Since we don't want to automatically refresh ever, we just added a way to request it, since we know in this test that we're doing something, effectively, out-of-band, which necessitates it.
