This PR fixes the problems to clear a section with a question included.

Example Code:

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $section1 = $output->section();
        $io = new SymfonyStyle($input, $section1);

        $output->writeln("foo");

        $countdown = 3;
        while ($countdown > 0) {
            $section1->clear();
            $io->writeln('start ' . $countdown);
            $io->write('foo');
            $io->write(' and bar'.\PHP_EOL);
            $givenAnswer = $io->ask('Dummy question?');
            $section1->write('bar');
            $countdown--;
        }


        return self::SUCCESS;
    }

There was already a fix #48089 to be merged in 6.1, but the problem was that there were some changes in 6.2, so it was not possible to merge it into 6.2.

So this fix is only working for 6.2, but perhaps we could find a solution as well for the older versions. But because of the changes of console it was not possible to find a solution working for all versions.

@chalasr this fix is still with the newline always true

To make it easier to test is here a zip with 2 testcommands in the root and the changed vendors.
