Receiver in listen mode does not end after receive of count messages

[rkubis]

1. Start receiver in listen mode to receive one message:
   cli-rhea-receiver -c 1 --timeout 100 --log-msgs dict --recv-listen true
2. Send one message:
   cli-rhea-sender -c 1 --log-msgs dict --msg-content "hello"
3. Receiver is still listening and waiting for messages although one message is received.
