Uncontrolled errors

[tn]

Hello,
thanks for this great project.

I have had some issues during making bot which was created with telegram-bot-now.

1. If you define commands in BotFather, in group chats commands will called like /cmd@mybot. Commands doesn't work in this case. You need to define cmd@mybot command in routes too. That's insane.
2. Any media attachment causes error: An unexpected error has occurred. The bot /owner has been notified.
3. Inviting bot to group causes error too. I think any non-text message causes error.

My server.js look like:

const self = {
	start: () => {
		return 'Some text'
	},
	undefined: () => {
                // hack: mute errors about invalid messages
		return
	},
	cmd1,
	cmd2,
	cmd3,
	cmd4,
	'cmd1@mybot': cmd1,
	'cmd2@mybot': cmd2,
	'cmd3@mybot': cmd3,
	'cmd4@mybot': cmd4,
	MSG: {}
}

Any advice, solution?
