Streamline pcrud a bit.

Streamline pcrud a bit.

If there is a permacrud entry for the relevant action, but the list of
permissions is empty, we grant access.

The change: grant access as soon as the permission list can be known
to be empty, instead of doing a lot of irrelevant stuff first
(including extra database fetches in some cases).
