    Plug a placeholder leak in the box adaptor
    
    gtk_widget_destroy() is not the right counterpart for
    g_object_ref(), and it is useless anyway to do a ref-unref
    pair around gtk_container_remove(), so just drop this.
    
    This fix makes the placeholder instance count go down again
    when shrinking the size of a box.
