Subject: Rich Media: Skip Microformats hashtags

When fixing this problem I incorrectly assumed a.hashtag is
the proper way for detecting hashtags, but it is just something Pleroma and
Mastodon add. Per microformats it should be detected by the presense of rel=tag.

This MR adds a check for rel=tag, but I still left a.hashtag just in case
