I also noticed this bug recently. I find it very annoying to get system emails now whenever unattended-upgrades is scheduling a reboot. It should either be fixed in systemd (why are they writing an info message to stderr?) - or if it can't be fixed there, at least unattended- upgrades should redirect the output of the shutdown command to avoid these messages.
