Make media storage optional 
If generating the SelectedMediaStorage configuration results in an
error (because there is no MediaUrl or Bunny CDN is not configured)
then don't configure the `/media` end-point, and make sure that the
`/micropub?q=config` query does not return a media-endpoint URL.

Better support for Quill's "favorite" request 
Quill doesn't send a `content` parameter along with the `like-of` data
when performing a "favorite" request.
