    clutter-id-pool: fix warning on bad pick
    
    Commit 13ac1fe7 purported to extend the _clutter_id_pool_lookup()
    warning to the case where the id referred to a deleted actor, but did
    not actually do so, because _clutter_id_pool_remove() set deleted IDs
    to 0xdecafbad, not NULL. Fix this.
