Bug 20652: Fix result sorting after search on limit only

Bug 20652: Fix result sorting after search on limit only

1 chomp was missing, spaces were replaced with %20
This patch adds extra chomps, but it does not hurt

Test plan:
Advanced Search
Choose an Item type (do not enter any other search limits)
Search
Click on Sort (it doesn't appear to matter what you sort on)
