Subject: [PATCH] Ticket 49380 - Crash when adding invalid replication 
 agreement

    Bug Description:  If you add a replication agreement with an invalid "replicaEnabled" value
                      the server crashes when freeing the replica schedule.  This is because the
                      schedule never gets allocated before the rror conidtion is hit, and then
                      it get dereferenced.

    Fix Description:  Check for a NULL schedule before trying to destroy it.
