Don't forward author_name to edition search yet; needs full reindex

[cdrini]

Side-effect I accidentally introduced in the last deploy. The author field, up until the last deploy, was kind of ignored during the edition-matching query, since the authors aren't stored on the edition. I sort of changed this during the last solr reindex, but as a result of some errors that happened, it didn't fully take effect. So now some editions in solr have authors, some don't. #8191 in assumes they do have authors, so it might be forwarding it along, causing the edition match to fail.
