Since everyone can send a private message to any user/bot
in Telegram, this method allows to set a list of whitelisted

to interact with the bot the command is not parsed and instead
the bot will inform that user that he is not allowed to talk
with the bot.
We also set self.latest_update to +1 in order to get the next
available message (or an empty {} if no message has been received
yet) with the method self._get_messages().
