    Fix the colord support in GtkPrinterCups when the PPD is loaded async
    
    If the PPD is not available when the printer is loaded then the PPD options are
    not available and we can't get the correct qualifier to use with colord.
    
    When the PPD becomes available, refresh the profile title to reflect reality.
