Throwing NotFoundException results in 500 error page

[toebu]

Description

When throwing a Kirby\Exception\NotFoundException, an error page is rendered as if an internal server error would have happened with an http status code of 500.

Expected behavior
Render the 404 page, with a 404 http status code.

To reproduce

1. Take the Kirby Starter Kit
2. Add the following to the config:

    'routes' => [
        [
            'pattern' => 'test',
            'action'  => function () {
                throw new NotFoundException();
            }
        ]
    ]

3. Go to http://localhost/test

Or alternatively

1. Take the Kirby Starter Kit
2. Edit site/controllers/notes.php to include throw new NotFoundException(); right at the beginning of the returned function.
3. Go to http://localhost/notes

Or even worse

1. Take the Kirby Starter Kit
2. Go for example to http://localhost/media/pages/photography/trees/1

In this last case, the NotFoundException is thrown from Kirby internally with the message "The thumbnail configuration could not be found".

I'm not sure if I should report a separate bug, because you can basically enter anything starting with http://localhost/media/pages/photography/trees/... and it will log a NotFoundException, even though it should just render a normal 404 page without logging anything.

About media link issue is solved in #6446 (will be available 4.3.0)

I was also realized that NotFoundException returns 500 http header instead 404 in that issue. I'm not sure this is bug or not.
