Bug 15216: Returns - Show collection description

Bug 15216: Returns - Show collection description

The table of returns displays the collection code
instead of the description. This patch fixes that.

Same as first patch:

To test:
- Check out some items
- Return the items
- Verify the changes in the table of returned items
