In Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntityValidator.php, according to documentation (https://symfony.com/doc/current/reference/constraints/UniqueEntity.html#message) it is possible to use the __toString method when used field is an object.
However the formatWithIdentifiers method never return the __toString method result.
Is it possible to add this feature?
