Bug 21589: Series link formed from 830 field is incorrect

Bug 13692 corrected the series link for records using a 490/800 combination

When a record has a 490/830 conbination for series, the link is malformed (title is used as author, title is blank)

Test Plan:
1) Catalog two or more records with 830 fields
2) Note the series links are broken
3) Apply this patch
4) Reload the record details page
5) The series link should now work
6) Repeat for the OPAC
