Please provide reproducable code

To reproduce:

1. Fire up the "ping" sample.
2. Create a telegram channel (in my case it was a private channel, but I doubt it matters).
3. add the bot to the channel. Allow it to receive messages.
4. send any message on the channel.
5. watch the poor bot die.

If you change line 93 to:

if(data.from !=null) 
  this.member = this.chat.members.add(this.chat.id, { id: data.from.id, extras: [{ user: data.from }] }); 

Then channel messages work.

I think that channel messages are just from the channel, not from a user.
