DARKMODE seems to be wrong if the state changes while the computer is shut down

[huyz]

1. Let macOS auto-switch to dark-mode (via the Night Shift schedule)
2. Shut down the computer
3. Shut down your mind and go to bed
4. Wake up and wake your computer, at a time when the Night Shift schedule would have switched macOS to light mode.
5. dark-mode-notify still returns DARKMODE=1
