* Ensure replied-to is a status not a boost
* Consider case of not a reply
* Add test case for replying to boost
* Move reblog-reply resolution to model
* Remove unnecessary comment
* Add profile to json+ld in Accept
It's required by the ActivityPub spec
* Use headers['Content-type'] instead of mime_type
mime_type strips the profile from the content type, but it's still available raw in the headers hash
* Add test for ld+json with profile
