Description:

Error when using createUrlCallback variable in ResetPassword class

Steps To Reproduce:

1. Create an notification with php artisan make:notification BlaBlaNotification

2. Eextends ResetPassword class in the BlaBlaNotification
   class TestResetPassword extends ResetPassword
   and remove all methods

3. Create a variable of static::$createUrlCallback and assign "test" value
   public static $createUrlCallback = "test";

   and created a function on name is "test"

   public function test(){
   	dd("stop");
   }
   

got an error when I send the request to the controller class containing the the BlaBlaNotification

Controller
Notification::send(User::first(), new BlaBlaNotification("foo"));

The error:
TypeError: call_user_func(): Argument #1 ($callback) must be a valid callback, function "test" not found or invalid function name in file C:\blabla\vendor\laravel\framework\src\Illuminate\Auth\Notifications\ResetPassword.php on line 119

I typed function_exist(static::$createUrlCallback) on line 93 in the ResetPassword class and saw it returned "false"
For this reason, I thought that the call_user_func function could not reach the "test" method in the BlaBlaNotification class.
