#6 Search results are sometimes appended when the old list should be cleared instead.

How to reproduce 1. search something. Wait till search ended. 2. click `X`, will start a new search. 3. click `back` button to hide keyboard **before** search in `2.` is finished This seems related to the change of visible space when the keyboard is shown/hidden. What is likely causing the problem: when the list is reaching the bottom, an automatic request is sent to fetch more radios. The new request is sent because hiding/showing the keyboard fires a new "onScroll" event. Since each new requests kills all previous ones (even if they've not completed), this new automatic request is interpreted as "get more results" instead of "get new results".
