Bug 15808 - Remove "Return to where you were before" from sysprefs

This patch removes the link 'return to where you were before' from
syspref search result page after failing search.

To test:
- Apply patch
- Go to System preferences in staff client, do a search
  with something that does not exist
- Verify that a message pops up that does not contain the link.
