Description:

When running a phpunit test that calls $this->visit('...'), VerifyCsrfToken.php is failing to call $this->addCookieToResponse($request, $next($request)) (line 64) because $next($request) is returning null. It's my understanding that $next($request) should return a response object.

Steps To Reproduce:

1. Create phpunit test that calls $this->visit('...')
2. Run test without using withoutMiddleware()

Stack:
