D-Bus: notify properties changed from fakes

D-Bus: notify properties changed from fakes

Call the property changed callback when fakes use ReplaceValue() or
ReplaceValueWithSetValue(), since the actual implementation will
always call the callback.

This avoids issues with property changed notifications being missing
when properties structures are built within fakes.
