Bug 3337 - RSS link is not correct for searches without results

RSS links for searches without results didn't have the search terms.

To test:
- Search for something with results and check RSS link
- Search for something with no results and check RSS link

In both cases your search should show up in the link.

RSS Link works in both cases listed in test plan.
