present: Do not replace Pixmaps on redirected Window on unflip
When unflipping, we may find that our flip window has been redirected. If we replace the redirected Window with the Screen Pixmap we then have mutliple fullscreen Windows believing that their own the Screen Pixmap - multiple fullscreen Windows that are being flipped by Clients, and so continue to flip causing popping between e.g. the compositor and the game.
