@Nullable public PersistentEntity<?,?> getEntityUltimatelyReferredToBy(PersistentProperty<?> property)
PersistentEntity
the given PersistentProperty
refers to in case it's an association.
For direct aggregate references, that's simply the entity for the PersistentProperty
's actual type. If the
property type is not an entity - as it might rather refer to the identifier type - we either use the reference's
defined target type and fall back to trying to find a PersistentEntity
identified by the
PersistentProperty

PersistentProperty
ultimately refers to. In case it's of a unique identifier
type of an entity known it'll return the entity type.property
