Imports may be associating new Editions with /type/redirects Works

An item on archive.org linked to this Work ID.

### Details

1. Any edition imported and attached erroneously to a `/type/redirect` work will **not** show up in search
2. We likely need to fix our Import pipeline to check first whether a work is a `/type/redirect` (and this is in something like `openlibrary/catalog/__init__.py`)
3. We likely need to clean up these http://openlibrary.org/query.json?type=/type/redirect&subjects~=*&limit=1000 <-- this will need to be pages over as there are more than 1,000 results and 1,000 is the query limit.
