Validation fails when using Validator::passes() or Validator::fails()

[Thungdemo]

First of all thank you for this great and easy to use captcha package.

VERSION PHP version 7.1.22 Laravel version 5.4 Package version 2.1.0

ISSUE Captcha validation fails when using $validator->passes() or $validator->fails() inside a FormRequest class. I have a request validation class which always throws the 'Invalid code from the image' error

namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;

class MyRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }
    public function rules()
    {
        return [
            'captcha' => 'required|captcha',
        ];
    }

    public function withValidator($validator)
    {
        if($validator->passes())
        {
            //do something
        }
    }
}

LIKELY CAUSE Running $validator->passes() or $validator->fails() runs the validation again, but the captcha session is likely cleared in the first validation which causes the validation to fail when run for the second time.
