Bug 33160: Use hostinfo to display title information when 773$w is empty

When a 773 entry is not linked to another record using 773$w or
by using Easyanalytics, the title information would not display.

To test:
1. Activate the UseControlNumber system preference
2. Search for a record and make sure it has 001 set to some value.
3. Use Edit > Add child record to create an analytical record from this record.
4. Make sure 773$w was filled in and finish by adding any mandatory fields, save.
5. Add this record to your cart. Also add a 773$g with the pages or similar.
6. Create another record with 773$t and $g, but without $w.
7. Also add this record to your cart.
8. Look at the cart brief and full view in staff and OPAC.
9. Verify the In: source information only displays for the first record.
10. Apply patch
11. Veriy the In: source information now displays for both records on all 4 pages.
