Redirects return blank page with HTTP 200 status

[zimozy]

I couldn't perform redirects:
return $response->withRedirect('/page');
I'd get a blank page with an HTTP 200 status code.

I was able to fix this on my machine by changing
$next($request,$response);
to
$response = $next($request,$response);

(Since the Response is immutable as per the user guide.)

Thanks @zimozy for finding this. I bumped into the same issue. @christianklisch, is this still something you want to maintain? Middleware under Slim 3 requires the solution that @zimozy suggested.
