if the deleted node was "below" this path, then do not unref all nodes

Fri Apr 26 21:58:16 2002  Kristian Rietveld  <kris@gtk.org>

        * gtk/gtktreemodel.c (gtk_tree_row_ref_deleted_callback): if the
        deleted node was "below" this path, then do not unref all nodes
        between the deleted parent and the node this rowref is pointing too
        (see added comment in gtk_tree_row_ref_deleted_callback),
        (fixes #77977)
