This change includes:
- Improve the spec coverage for incoming request to the webfinger action
- For requests without an accept header (ie, what a browser might look like),
return a JSON response.
- For requests with an explicit format of xml or json, return that format.
- For requests using an accept header, return that format.
Also adds failing spec showing webfinger does not return xml, which covers the
issue described in: https://github.com/tootsuite/mastodon/issues/1983
* Add request spec for host meta route returning xml
* Add routing spec for xrd routes
* Update well-known routes
* Move webfinger and host-meta actions to their own controllers
