rosstimothy 4f569a4a63 Prevent blank revisions from being read from the backend (#32871)
* Prevent blank revisions from being read from the backend

Overwrites any empty resource revisions with a placeholder value to
prevent any blank revisions from being provided to users.

* Prevent backend items with empty revisions

All resource revisions are now being set on a backend.Item before
persisting the item to the backend.
