Also add stanzas to unacknowledgedStanzas while shutting down

Browse source 
This caused the WaitForClosingStreamElementTest integration test to
fail, because the last presences stanzas, which are send after done()
in the writer thread would return true, are not added to the
unacknowledgedStanzas queue.

The result was:
