If a GESTimelineFileSource is added to a layer and: * It doesn't have specified supported formats * OR it doesn't have a specified maximum duration * OR it doesn't have a specifed duration Then we asynchronously send it to the GstDiscoverer. If this happens, the state change of the timeline from READY to PAUSED will happen asynchronously and be completed when everything has been properly discovered. Part 2 of GstDiscoverer integration
