Changes into new added question onQuestionAdded event generates addition undo transactions

[andrewtelnov]

If there is a code like this:

  creator.onQuestionAdded.add(function (sender, options) {
    options.question.title = "new title";
  });

then it would require to click two times on "Undo" to remove the question. Changing title will be added as a new undo transaction. If there are several properties changes, then more "Undo" clicks would be required.
The same story with onPageAdded and onPanelAdded events.
