core: Can't serialize Ramsey\Uuid\Uuid identifier

When api-platform try to serialize my entity, I get the Resource "Ramsey\Uuid\Uuid" not found. error. It seems to only happen on deep serialization. In the following stack trace, I’m exposing AppBundle\Entity\Theme entities which have a bidirectional ManyToOne to a AppBundle\Entity\Category.

Also, I tried to expose my AppBundle\Entity\User entities which use the same identifier configuration and serialization works well when using application/json format but not application/ld+json format.

Stack trace:

[1] ApiPlatform\Core\Exception\ResourceClassNotFoundException: Resource "Ramsey\Uuid\Uuid" not found.
