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

[facchinm]

if ((screen.width != screenW) || (screen.height != screenH)) in Base.java 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
