Title: Display formatNoMatches when all ajax results are selected

I've implemented this 3-liner in the postprocessResults method.

I'm thinking a better approach would be to filter out already selected results in the moment they are received from the server. But that would require far more change and I wasn't entirely sure what it would entail so I kept it simple.
