Ticket 47620 - Unable to delete protocol timeout attribute
Bug Description: Attempting to delete nsds5ReplicaProtocolTimeout from a replication
agreement unexpectedly fails with an error 53.
Fix Description: The previous delete operation check was in the wrong location, and the
delete operation was treated as a modify - which then triggered the
error 53. Added the correct check for the delete operation.
Also removed some old code for a CLEANALLRUV attribute that was never
implemented.
