    app: Fix gimp_dock_separator_get_insert_pos(), we must return an index
    
    The insert position for new column in GimpDockColumns was sometimes
    wrong, the problem was in gimp_dock_separator_get_insert_pos() not
    return an index but a GtkAnchorType. Convert from GtkAnchorType to an
    insert index.
