Ping erg on this. I think there is a better way to go about this rather than
ifdefing the two methods.

   return static_cast<SessionService*>(
       GetInstance()->GetServiceForProfile(profile, true));

   SessionServiceFactory* factory = GetInstance();
   factory->GetServiceForProfile(profile, true);
