    local-metadata: don't double-free cancellable
    
    resolve_album_art() is "balanced" with respect to the cancellable's
    refcount: it exits with 1 reference to the cancellable owned by
    the operation_id, having arranged for that reference to be destroyed
    by a GDestroyNotify when the operation_id finishes. There
    is no need for resolve_album_art_cb() to release the same reference.
