Error on form normalization

[jcerri]

I got the following error when normalizing a form containing SubmitButton with the InitialValuesNormalizer :

Argument 1 passed to Limenius\Liform\Serializer\Normalizer\InitialValuesNormalizer::getValues() must be an instance of Symfony\Component\Form\Form, instance of Symfony\Component\Form\SubmitButton given, called in my-project/vendor/limenius/liform/src/Limenius/Liform/Serializer/Normalizer/InitialValuesNormalizer.php on line 62

The getValues() function requires a Form but the SubmitButton is not one but implements FormInterface.
In my case, replacing Form by FormInterface does the job but may require further testing.

This issue is still here, working on Symfony 5.4
