Revert b2a459edf "Fix GRANTED BY support in REVOKE ROLE statements"

The reverted commit attempted to fix SQL specification compliance for
the cases which 6aaaa76bb left.  This however broke existing behavior
which takes precedence over spec compliance so revert. The introduced
tests are left after the revert since the codepath isn't well covered.
Per bug report 17346. Backpatch down to 14 where it was introduced.
