Add locality check to ActivityPub::FetchRemoteAccountService (#9109)

* Add locality check to ActivityPub::FetchRemoteAccountService

Fix #8643

Because there are a few places where it is called, it is difficult
to confirm if they all previously checked it for locality. It's better
to make sure within the service.

* Remove faux-remote duplicates of local accounts
