If no Ignore annotation is used, the attributes for serialization are obtained using `Symfony\Component\Serializer\Normalizer\ObjectNormalizer::extractAttributes`.
There it is checked if the method has required parameters and if yes, the method is ignored.

However, if you use the Ignore annotation, the attributes are determined with a different method. Here I have adapted at least for get methods the behavior as it was before.

If someone serialized a class with Ignore annotations before, he got here `\Symfony\Component\PropertyAccess\PropertyAccessor::readProperty` an exception as written in ticket #46592. With this fix the methods are ignored and there is no exception anymore.
