Same URI passed between follow request and follow, since they are
the same thing in ActivityPub. Local URIs are generated during
creation using UUIDs and are passed to serializers.
This makes slightly more sense, and ensures that the author of a post is always referenced in the audience (which some servers might rely on). And the announce is POSTed to the author's inbox anyways.
We had returned `nil` for that case, but this raises an error instead, as a wrong usage of the method.
This method is currently only used in ActivitySerializer.
In before, the method uses stream_entry id as status id, so replied status was wrongly selected.
This PR uses StatusFinder which was introduced with `Api::Web::EmbedsController`.
* Process Create / Announce activity in FetchRemoteStatusService
* Use activity URL in ActivityPub for reblogs
* Redirect to the original status on StatusesController#show
- Tries to avoid performing HTTP request if the keyId is an actor URI
- Likewise if the URI is a fragment URI on top of actor URI
- Resolves public key, returns owner if the owner links back to the key
