Don't restore sketch if last.sketch.location is out of display

`if ((screen.width != screenW) || (screen.height != screenH))` was making sure to reset every preference in case the display geometry changed.
Unfortunately, on Windows 10, `Toolkit.getDefaultToolkit().getScreenSize()` reports only the primary monitor either if external display is connected or not.

Fixes #9781
