Mehdi Abaakouk 8a644c1166 Don't reply to notification message
The notification listener doesn't have anything to send to the notifier
and the notifier doesn't attend to receive something.

So this patch remove the message reply when the listener is a
notification
listener.

Partial implements blueprint notification-subscriber-server
