ges: Let user set TimelineObject URI while not containing any TrackObject

In the case of not properly set uri, we can keep using the same
TimelineFileSource changing its URI until its TrackObject could be created.

This is particularly usefull in the case of formatter trying to load filesource
when the file has been moved
