[0.4.10][COMCTL32] Fix regression CORE-16280

The visible symptom for us was, that the Apply button in our
desk.cpl was always visible, even in case no user input was done in the dlg yet.

A very old regression. It regressed somewhere around
SVN r42990 – Good (2009-09-03)
SVN r44397 – Fail (2009-12-04)

The fix is a backport of 0.4.13-dev-908-g

Unchange the property sheet page after WM_INITDIALOG (#1842)
In my testing on Win2k3, EN_CHANGE is generated in OnInitDialog, that is correct.
The target is property sheet.
The property sheet does unchange the page after WM_INITDIALOG generation.
