Undoing after saving as

[Casper Boemann]

To me it looks like the problem is that you copy the image but the 
magicconverter works on the original including the undoadapter of the 
original

	KisImage * img = new KisImage(*output->currentImage());
	Q_CHECK_PTR(img);

	KisImageMagickConverter ib(output, output->undoAdapter());

	img->flatten();
