    Engine-Twitter: handle IOException inner-exceptions
    
    Twitter has every day IOExceptions thus they need to be treated like temporary
    issues and not permanent issue.
    
    Example:
    
        2021-01-20 05:08:54,628 [TwitterProtocolManager friends timeline listener] ERROR 
Smuxi.Engine.TwitterProtocolManager - UpdateFriendsTimelineThread(): Exception
    
        System.Net.WebException: Unable to read data from the transport connection: Connection reset by peer. 
---> System.IO.IOException: Unable to read data from the transport connection: Connection reset by peer. ---> 
System.Net.Sockets.SocketException: Connection reset by peer
    
          at Smuxi.Engine.TwitterProtocolManager.CheckWebException (System.Net.WebException exception) 
[0x0008d] in <b07886f794b444e6a88ef1ae4c9ed942>:0
