[Bug]: Multiple authors from matched tab are set as a single author instead of separate authors

[kymahi]

Describe the issue

When matching a book, if the book has multiple authors (comma separated typically), the author field will be populated with [John Smith, Joe Schmo] instead of [John Smith], [Joe Schmo]

Steps to reproduce the issue

1. Add a book with multiple authors to server
2. Edit newly added book
3. Navigate to Match tab
4. Search for book on any source
5. Find matched book and select it
6. Save changes, allowing overwriting
7. See that there is a single author entry with two, comma-separated names instead of two authors

I believe this same issue is occurring with podcasts and the "Genres" field. I was matching on "Dan Carlin's Hardcore History" podcast, it had genres "History,Podcasts" and that failed to update with this error:

Removing the "Podcasts" genre along with the comma allowed it to import.
