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.
