Invoking "errors" method causes fatal error

After calling the "passes" method to validate data, calling the `errors()` method triggers a fatal error by attempting to invoke the `all()` method on an array.

My example code

```
$data = $this->request->json();
$this->validator->with->data($data)->passes(ValidatorInterface::RULE_CREATE);
$this->validator->errors();
```

The error

```
PHP Fatal error: Call to a member function all() on array in /var/www/my.app/vendor/prettus/laravel-validation/src/Prettus/Validator/AbstractValidator.php on line 92
```
