User message sending error

[simonevann]

Sometimes users have not filled in the last_name and username attributes, so Telegram passes a None value.
This leads to an error in the media_handlers.py file starting from line 65.

        new_message_data = cls(
            message_id=message.id,
            user_info=UserInfo(
                id=sender.id,
                username=sender.username,
                first_name=sender.first_name,
                last_name=sender.last_name
            )
        )

You should handle the None exception by inserting a string. Unfortunately, I don't feel skilled enough in Python to make a Pull request :)

I solved it like this locally:

    new_message_data = cls(
        message_id=message.id,
        user_info=UserInfo(
            id=sender.id,
            username=sender.username or "",
            first_name=sender.first_name or "",
            last_name=sender.last_name or ""
        )
    )
