quick frontends (contact list): ignore roster entities with a resource:

cache uses bare entities, as a result when a jid with a resource is used in roster, it is not handled properly.
As this case is rare and probably resulting from bugs in clients, entities with resources are ignored and a warning is logged when this happens.

fix 306
