[folks] Properly serialize AFD values for the Tp cache.

    Properly serialize AFD values for the Tp cache.
    
    We were previously writing serialized Telepathy AbstractFieldDetails
    values over each other in the final array, which was generally bad
    and specifically crashed Gnome Shell.
    
    This affects AFD-derived structures: phone numbers, email addresses,
    and URLs.
    
    Closes: bgo#662314 - Gnome-shell restarts if I change my user status to
    disconnected/unavailable
