Some telegram user attributes are optional

[IdrisN]

The method checkAndGetResponseData(...) checks if all of the following attributes are available: ['id', 'first_name', 'last_name', 'username', 'photo_url', 'auth_date', 'hash'].

last_name is an optional attribute though. This leads to a NotAllAttributesException although the received data is potentially valid.

I haven't tested it jet, but i assume that photo_url is also not set if the user does not have a profile picture.

Hey, thanks for catching this!

Seems like Telegram didn't state this at all...
After thinking about this, I don't think this check is necessary at all - I'll make a pr that removes this check completely.

Thanks!

Released v1.2.1 to take care of this. Thanks for spotting it!

Awesome!

That was a fast response. I've already started fixing the check and was just about to open a pr but was a couple minutes last i guess :D
