[PATCH spice-gtk 31/34] spicy: use SpiceSession::disconnected signal

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

Let's not track channels ourself, but rely on the disconnected signal
instead.

This solves spicy hanging, when gstaudio is recording and the main
loop is gone, so record channel is not finalized, and GStreamer
locks.
