Subject

Extending RequestPasswordFormType occures error while accessing to email property

Steps to reproduce

Extends form using getParent() :

    public function getParent()
    {
        return RequestPasswordFormType::class;
    }

Expected results

Form printed like FOSUserbundle did.

Actual results

Neither the property "email" nor one of the methods "email()", "getemail()"/"isemail()"/"hasemail()" or "__call()" exist and have public access in class "Symfony\Component\Form\FormView".

[core23]

This feature does not exist, because there is no RequestPassword model class to map this data.

Feel free to provide a PR which add this feature @fodger .
