dbusServices/screencast: Handle pipeline failures gracefully

Browse Source 
If parsing the pipeline fails for some reason, we currently end up
with a zombie session that leads to a stuck recording indicator in
gnome-shell.

Instead, properly tear down the session to allow mutter and gnome-shell
to correctly update their state.
