gstpipeline: fix failed assertion caused by seeking pipeline with NULL clock
Under certain GST_STATE_CHANGED_PAUSED_TO_PLAYING transitions, a pipeline with a NULL clock will fail an assertion due to an unchecked call to gst_object_ref(). This is fixed by simply adding a check and only ref-ing if the clock is not NULL. https://bugzilla.gnome.org/show_bug.cgi?id=693065
