telegram-chat: ignore new messages after reboot

This script supports multiple devices, and sending offset to discard
messages is delayed to third fetch to make sure all devices get the
message.

This can cause trouble, though: Sending a device a reboot command can
make that device reboot multiple times 🥴 or - even worse - make it
enter an infinite boot loop 😳 if it is the only device.

So let's ignore first messages after reboot.
