[polling] Fix stopping polling

Browse Source 
Bug:

  TelegramBot#stopPolling() fails to clear the timeout
  that is waiting to make the next polling request.
  Thus, if the method is invoked after the timeout has
  already been set up, once the timeout fn is executed,
  another request is made, before polling is stopped in the
  '.finally()' handler of the request!
