Federation: WebFinger request does not have Accept header set

[aral]

From Mastodon v2.1.0, I’m seeing WebFinger requests that do not have an Accept header set to application/jrd+json.

• I searched or browsed the repo’s other issues to ensure this is not a duplicate.
• This bug happens on a 2.1.0 – cannot test on latest release right now due to Mastodon can no longer be installed on Scalingo (image too large) #6491

@aral Since #6491 has been solved, could you please verify that WebFinger requests don't have Accept header set to application/jrd+json in some cases? Additionally, could you share some requests that lack this header?

Request.new(:get, url).add_headers('Accept' => 'application/jrd+json, application/json')
