    aisleriot: Fix card theme menu
    
    The order in which the card theme directories are scanned assumed
    that the first theme with a given pref name is retained, but
    the code actually replaced that one when further themes with the same
    pref name were found. Fixing that fixes the card theme menu in
    aisleriot to show the current theme correctly.
