DropboxRestException with message "Received Response [0] : Expected to see []. The HTTP response was []" in GetLongpollDelta #150

I have a DropboxRestException with message Received Response [0] : Expected to see []. The HTTP response was []" when I do a longpoll delta. The exception occurs after the timeout I pass to the GetLongpollDelta method.

To reproduce, just setup a long poll delta and wait without doing any change in your dropbox. It seems that the request timeout before receiving a response from dropbox saying that there is no change. The longpoll feature is pretty much useless if all the requests timeout...

As a workaround, I increased by reflection the timeout property of the _restClientNotify field of the DropNetClient
