Remove if condition in _run_handlers

Hi

The if condition in _run_handlers is creating issues, when I try to test tgvoip example. I modified it as

    def _run_handlers(self, update: Dict[Any, Any]) -> None:
        if update.get('@type') == 'updateNewMessage':
            for handler in self._message_handlers:
                self._workers_queue.put(
                    (handler, update),
                    timeout=self._queue_put_timeout,
                )
        else:
            
            for handler in self._message_handlers:
                self._workers_queue.put(
                    (handler, update),
                    timeout=self._queue_put_timeout,
                )

or we can create another method for add_message_handler like add_call_handlerand append functions to new list like _call_handler. In else condition use it.

If ok, I can create a PR.
