Fix a bug that 'change' event is not dispatched after unselecting an OPTION via accesskey.

We should use selectOption(-1) in a case of unselecting menulist.

Add "accessKey" modifier to eventSender.keyDown() for testing.

Also, code cleanups:
 - Early return for |listIndex < 0| and |!isHTMLOptionElement|.
 - Remove unnecessary dispatchInputAndChangeEventForMenuList() call after selectOption().
 - scrollToSelection() is necessary only for listbox.
