Fixed issue with caching for mini keyboard views: Getting 'miniKeyboardView' from 'mMiniKeyboardCache' and not from the previously shown layout. Fix #251.

+ removed mMiniKeyboard!!.mOnKeyboardActionListener is not needed in MyKeyboardView.onLongPress() func. Originally defined in SimpleKeyboardIME class.
