--telegram-chat can't handle negative sender_chat id values

[nheinemans]

Adding a bot to a channel (as admin) and mentioning the bot with a /start, this results in a negative sender_chat id value. Urlwatch --telegram-chat can't handle this, resulting in an error message:

Confirmed this is an issue in the reporter as well:

% urlwatch --test-reporter telegram Telegram error: Bad Request: chat not found

This is resolved in the webchanges project and should work here too! Instead of using the negative chat id, just use the @channelusername like this:

  telegram:
    bot_token: '1234567890:iuasdhoaihofgojsdfoifasofsoiabsfoi'
    chat_id:
      - '0987654321'
      - '@channelusername'

Thanks @mborsetti !

Does this only apply to "channels" (i assume group chats) and not "users"?
