QPID-4223: HA Completion isn't sent when queue that has acquired but unacknowledged messages is deleted

- Extended ha_test.py test_failover_send_receive to kill backup as well as primary
- QueueRegistry::destroy was not calling observer.
- Primary removes disconnected brokers backups and expectedBackups
- Primary calls checkReady in all cases where broker is removed from expectedBackups
