Set Witty Pi schedule to ON between 2019 and the start of the current week

[JonasBchrt]

Sometimes, the Witty Pi RTC (real-time clock) seems to reset to 2019. The system then stays off since we only program it to switch on during the current week in 2024. If we would program the Witty Pi to be ON for any time before the current week, the system may stay on in case of an RTC reset and we would have the chance to fix it remotely. Or it could fix it by itself, e.g., by getting the current time from the network.
