Fix T98305: Image.save not working for generated images with filepath

This is a place where the API function and operator should differ, for the API
manually setting the filepath and then saving should work. For the UI there is
no filepath visible, so it should open Save As even if there was a filepath set
for example from before changing an image type to Generated.
