What about having a SetUserNotificationCenterForTests instead? Reduces logic for
whatever creates this object.

Cross-platform tests could be written by using the factory's
SetTestingFactory().

The usual pattern for testing has usually been to inject the objects you are
planning to mock since that helps wi. This would make writing a unit test for
NotificationUIManagerMac very straight forward and would not require to add
special code to handle the test pieces in the actual file.

I don't feel to strongly about it though. 

Ok, I think injecting is nicer but this will in fact reduce the friction for
cross platform tests. I will resurrect the one I've removed from
platformnotificationserviceimpl as well then.
