WHY
Way to reproduce it : continuously scroll rsb and open new screen which has picker in it. Before picker is initialised, if it receives a rotary event , it crashes.
Another way to test is to revert changes in PickerRotaryScrollAdapter and launch RotaryInteractionTest.scrollPicker_receiveRotaryEventsBeforeInitialisation test.
