[CUPS] If no printers is auto-discovered, show the manual printer setup dialog

[CUPS] If there is no auto-discovered printer, show the manual printer 
setup dialog.

When setting up a printer for CUPS (Settings -> Printers -> Add Printer),
the default dialog should be "Add a nearby printer" via auto-discovery.

However, we should account for the case where no printers are available 
via auto-discovery - In this case, if 0 printers are detected, we should 
present the "Add a printer manually" to avoid presenting a dialog with an 
empty list of printers.
