Fixes #360
Instead of passing a missing body to the view do an early exit if a redirect is encountered.

Can anyone tell me why the CI is not running or what I have to do?

@sdelamo Can you maybe help out here?

A workaround would be return

HttpResponse<?> index() {

if (blabba) {
return HttpResponse.ok(new ViewModel(.....));
}  else {
return HttpResponse.seeOther("/foo");
}
}
