sdl2: fix crash in handle_windowevent() when restoring the screen size
The Ctrl-Alt-u keyboard shortcut restores the screen to its original size. In the SDL2 UI this is done by destroying the window and creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when it's destroyed, but trying to call SDL_GetWindowFromID() from that event's window ID returns a null pointer. handle_windowevent() assumes that the pointer is never null so it results in a crash.
