removed assertements for constructed containers again, since this

        * gtk/gtkcontainer.c:
        (gtk_container_add_with_args):
        (gtk_container_addv):
        (gtk_container_add): removed assertements for constructed containers
        again, since this essentially breaks the "child" arg.

        * gtk/gtktooltips.c (gtk_tooltips_force_window): fixup the draw_window
        reference count, we don't need to reference toplevels that already have
        destroy notifiers.

        * gtk/gtkscrolledwindow.c: check for the composites existance in
        _forall since we might not be already constructed.
