Hibernate ORM / Bug HHH-8571
Revision queries broken for @ElementCollection of @Embeddable with nullable properties
1. Create an audited @Entity with a list of @Embeddable components. Make sure the @Embeddable class has a nullable property.

2. Create multiple revisions of an entity without populating the nullable property of any component.

3. Query for a specific version of the entity with AuditReader.find. Observe that the list of components is always empty.
