objects: Send a vlc_object_kill from vlc_object_destroy() to make sure vlc_object_release() can properly free all the allocated resources when the refcount reach zero.

Previously you need to send a vlc_object_kill() prior to a vlc_object_release() to get your object actually destroyed, which rendered the refcounting unusuable in some cases.
