spice: fix double unref of main channel

When doing unref() on a channel, channel-destroy signal may be emitted
during object dispose time, and it will attempt to unref() the channel
again likely leading to a crash.

It may be that spice-gtk should have a different/simpler object
life-cycle model, but it's also a good assumption to not take strong
references on the channels, but just keep a weak reference as the
session is really the channel life-cycle manager.
