Do not notify about property changes if the value hasn't changed
After 2ffb91ac592d69adf9458ac45074174537435918 we manually call notify()
for QObjectCompatProperties. Currently we always call it when setting
values to compat properties, even if the value hasn't actually changed.
Fixed to call notify() only if the value is being changed.
