A strange thing in parallel::sort.

Lines 210 to 214 in f63f4b9

	if (result.has_exception())
	{
	return detail::handle_exception<ExPolicy, RandomIt>::call(
	std::move(result));
	}

result(hpx::future) is returned from execution::async_execute(). So, if the task is running, result.has_exception() always returns false.

As I think, that code block(L210-L214) is not necessary because anyhow the exception which is occurred in the task is wrapped into the future(result).
