bizgres - bizgres: Fix DROP RESOURCE QUEUE so that it destroys the in

Log Message:
-----------
Fix DROP RESOURCE QUEUE so that it destroys the in memory queue along with
the catalog queue object. This does mean that it is possible to have foot gun
moments via ALTER ROLE ... RESOURCE QUEUE <none> for a connected user and then
DROP RESOURCE QUEUE on the role's queue. However this is no worse IMHO than
being able to do DROP ROLE on a role that is correctly connected!
