Fix an issue showing people who don't match typed query

If you type "Scott", my contact shows up as an option.  If you then
clear the field, and type "kj", and you don't have any "kj" contacts,
it doesn't clear the last set of contacts, so it shows you "Scott".

Now, we'll just clear the set when we get no results, so nothing will
show up.
