Akihiko Odaki 63f0979799 Validate id of ActivityPub representations ()
Additionally, ActivityPub::FetchRemoteStatusService no longer parses

OStatus::Activity::Creation no longer delegates to ActivityPub because
the provided ActivityPub representations are not signed while OStatus
representations are.
