onValid fires even when internal validation shouldn't pass

[andrewlorenz]

e.g.

handleValidForm() {
  console.log("I am valid");
}

render() {
  return (
    <Form onValid={this.handleValidForm}>
      <FormsyText name="email" required type="email" />
    </Form>
  );
}

onValid fires on every keypress, regardless of the type="email" validation that was requested.
