bluetooth: Handle UUIDs announced later

Browse source 
In some cases (typically during pairing) UUIDs might be reported by
BlueZ incrementally, that is, as soon as they have been discovered. At
this point module-bluetooth-device might already be loaded, so the late
UUID announcements need to be handled and additional card profiles
might need to be created accordingly.
