NumberPicker should adjust min and max when displayed values are set.

1. The BumberPicker exposes APIs for settings displayed values for the
   selected numbers. If the min and max value of the picker are less then
   the length of the new displayed values array, i.e. they are out of
   bounds, the NumberPicker crashes.
