title: Bot Framework doesn't have username if telegram profile doesn't have full name or username
body: <p>Messages delivered from Bot Framework don't have <code>name</code> property in <code>from</code> object if message was sent by user who doesn't have username and full name. For example if you delete first or last name from profile like that</p>
