Behaviour of default json deserializator was changed: in a case of "not found" server answer (JSON is valid, but does not contain any information) was rising error. Now it returns an empty collection.
1. In search view now it's not possible to send query when searching for an empty string
2. Keyboard can be hidden after result receiving in search and lookup view.
