`def deconstruct` defined twice in `django_jsonform.models.compat.JSONField`

https://github.com/bhch/django-jsonform/blob/master/django_jsonform/models/compat.py#L52

    def deconstruct(self):
        name, path, args, kwargs = super().deconstruct()
        kwargs['encoder'] = self.encoder
        kwargs['decoder'] = self.decoder
        return name, path, args, kwargs

    def deconstruct(self):
        name, path, args, kwargs = super().deconstruct()
        if self.encoder is not None:
            kwargs['encoder'] = self.encoder
        if self.decoder is not None:
            kwargs['decoder'] = self.decoder
        return name, path, args, kwargs

Yes, certainly a bug. We want to keep the second one.
