Naively it seems like we could keep this unittest and have it just test the
//components-level functionality, i.e., strip out all the stuff that is now
specific to the callback passed in by ChromeSyncClient. We could move just the
tests of the functionality that is specific into that callback into
profile_sync_service_factory_unittest. Is that doable/worth having?

[Nicolas Zea, 2015/11/11 00:06:20]

The way this test is written right now, it's really testing the component
factory's interaction with the PSS and the sync client, which really depends on
the ProfileSyncServiceFactory initializing them properly. We could write new
unit tests specifically for the component factory impl, but given the nature of
this factory, and the fact that it doesn't have much real logic in it, I'm not
sure how much that's worth it with this testing in place.
