[gnome-software] Load the small thumbnail if available when loading screenshots

    Load the small thumbnail if available when loading screenshots
    
    This broke when we switched to sha256'ing the URL for security, but if we do
    this we need to hash the _correct_ url for the thumbnail, not the URL for the
    main image as they may have a different URL path.
