convertframe: Fix async video sample conversion with non-default context

Browse source 
The GSource for dealing with timeouts in
gst_video_convert_sample_async() might be attached to a non-default
context, so we should not be using g_source_remove() on the returned ID.

The correct thing to do is to keep a reference to the actual GSource and
then call g_source_destroy() on it.
