INPUT element: Updating value to the previous defaultValue should dispatch "change" event.

INPUT element: Updating value to the previous defaultValue should dispatch "change" event.

We have set defaultValue to m_textAsOfLastFormControlChangeEvent only when input
type was determined, and updating defalutValue after it didn't update
m_textAsOfLastFormControlChangeEvent. So, 'change' event was not dispatched in
some cases.
