Audio connection do not stop properly
Expected behavior: Closing chat window by any of peers should terminate audio connection.
Observed behavior: When chat window with jingle audio connection is closed and voice (microphone) icon is not clicked before this action voice is not stopped. I can see in "gnome sound preferences" that sound devices are still used by gajim. If I make audio connection to myself (let say account A to B) I can still hear my voice from speakers after closing both chat windows.
When I reopen chat window (A to B) mike icon is in not marked/clicked state but if I click on it audio stops (it stops me from hearing my voice from speakers and remove gajim from list in gnome sound preferences).
