Hello, I tried to extend product repository like documented in sylius website I also tried to copy files from this repository, because I see the code differs a bit from the code in documentation. But in any case I get this error 'Cannot autowire service "App\Doctrine\ORM\ProductRepository": argument "$entityManager" of method "Sylius\Bundle\CoreBundle\Doctrine\ORM\ProductRepository::__construct()" references class "Doctrine\ORM\EntityManager" but no such service exists. Try changing the type-hint to one of its parents: interface "Doctrine\ORM\EntityManagerInterface", or interface "Doctrine\Common\Persistence\ObjectManager".'

We should change the README file to indicate legibly that it's a special Sylius repo with customizations 🚀
