    streamcollection: fix racy user-after-free

    The issue happens when the structure is printed by the logging
    subsystem: the object is included in the log, and this will cause the
    full object printout to be done there. However, after dispose, the queue
    was already cleared, so the access to it (to print the object) would
    assert, as the queue was already freed. The patch changes it so that the
    queue is merely empty, and only freed in _finalize.
