    app: do not update the tree view editable renderer when editing.
    
    When double-clicking the non-selected layer, the function
    gimp_view_renderer_set_border_color() was being called, which in turn
    called gimp_view_renderer_update() after some idle time.
    
    Unfortunately when this happened, the "update" handler
    gimp_container_tree_store_renderer_update() would call
    gtk_tree_model_row_changed() which triggers a focus out through GTK.
    
    One way to handle this would be to call gimp_view_renderer_update()
    directly when changing border color (no idle time), though it's actually
    more efficient to just cancel the idle function when we start editing
    the item name. It's just not necessary.
