api: Internal routing bug: doesn't work with middleware

Any internal request in conjunction with a route that contains middleware, like this:

$api->version('v1', ['middleware' => 'test'], function ($api) {

});

Results in a:

[ReflectionException]      
  Class test does not exist 

Despite it being define properly inside Kernel.php:

 protected $routeMiddleware = [
        'test' => \App\Http\Middleware\Test::class,
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    ];

I’ve created a test case to illustrate the bug here https://github.com/assembledadam/laravel

Just run php artisan testcase in the root folder, and to view the middleware working visit localhost/index.php/test/blahblah

Stack trace (from my application, not the test case!):
