Returns shifted chat ID (positive and without "-100" prefix).
Mostly used for private links like t.me/c/chat_id/message_id
Currently supergroup/channel IDs have 10-digit ID after "-100" prefix removed.
However, these IDs might become 11-digit in future. So, first we remove "-100"
prefix and count remaining number length. Then we multiple
-1 * 10 ^ (number_length + 2)
Finally, self.id is substracted from that number
