    timeline: simplify code to remove an object from the pendingobjects list

    g_list_remove_all () can be used as a simplification as the private data to
ges
    timeline object are 1:1.

    GESTimeline: Lock object discovery list

    TimelineFileSource objects are asynchronously discovered with discoverer
    with such objects being added to a pendingobjects list. If one were to
    remove a layer before an object in said layer had been discovered, a
    segfault could occur.

    As such, management of the list has been made more robust with the
    addition of a mutex and removal of the object from the pendingobjects
    list upon layer removal.
