smartlist: not found displayed when already in contact list

How to reproduce:

1. Search for one of your contacts
2. Wait 0-2s.
3. The smartlist contains both the contact and a "Not found" temporary item

Expected: Only contact is displayed.

Well, it turns out that the "Not found" temporary item is actually the search result of an earlier search. For example in this case I was searching for amarok, getting the amarok element + "Not found" for amaro.
