Sebastian Dröge ed1022fa81 Use gst_object_unref() / gst_object_clear() instead of the GObject ones
To allow the refcounting tracer to work better. In childproxy/iterator
these might be plain GObjects but gst_object_unref() also works on them.
In other places where it is never GstObject, g_object_unref() is kept.
