    pathbar: Don't reset current location menu
    
    Everytime there is a signal that the templates submenu or the extension
    menu items may have changed, we rebuild the whole menu anew.
    
    This is uncessary work and results in visible glytches, for instance
    when thumbnails are still loading.
    
    So, reset only the tumbnails submenu or extension submenu instead.
