resolved fdo#63805 max day of month of the intended month
Since 6619955e72c1c2f29a32e82478d19147c0d7610a Date::GetDaysInMonth()
operates on the normalized value that corresponds to the actual values
set at the Date instance, obtain and set number of days for the intended
month instead of using the rolled-over date.
