    userMenu: Force reload of background-image on icon changes
    
    When changing the user's avatar image, AccountsService will
    overwrite the old image with the new one, so the location
    returned by get_icon_file() is always the same.
    In order to pick up the change, we need to make sure to clear the
    previous image from both StTextureCache and StThemeNode's paint
    cache.
