    ChannelCollection: fix NRE that could happen when logging an exception
    
    The Console.WriteLine was deferrencing e.InnerException without checking
    if it was null first. Instead of doing this, we can just use "e.ToString()"
    which will print inner exceptions by default if they exist. The crash was:
    
    Unhandled Exception:
    System.NullReferenceException: Object reference not set to an instance of an object
