Since ReactHorizontalScrollView handles layout changes on JS side, it does not call super.onlayout due to which mIsLayoutDirty flag in HorizontalScrollView remains true and prevents scrolling to child when requestChildFocus is called. Overriding this method and scrolling to child without checking any layout dirty flag. This will fix focus navigation issue for KeyEvents which are not handled in HorizontalScrollView, for example: KEYCODE_TAB.
