I think there's no need for this -- GetProfileSyncService() already drills down
to the original profile IIRC

OK, I wasn't sure if this mattered. Definitely better if it does not - we drill
down to GetOriginalProfile() in about 4 places right now, and not in the other
couple of dozen. I will remove this and if we encounter any problems we can fix
GetProfileSyncService() instead.
