Sylius version affected: 1.12.0 to 1.13.2

Description

Hello, I'm upgrading a project from Sylius 1.12 to 1.13.2.

During the upgrade, I have set the enable_lazy_ghost_objects to true to remove deprecation.

But, if enable_lazy_ghost_objects is true I have an error when I try to access Sylius Ressource translation from a relation.

Related Issue : doctrine/DoctrineBundle#1809

Steps to reproduce

I added a new entity (resource) named Tag with a one-to-many relation to Product.

When I execute $tag->getFirstProduct()->getTranslation()->getName(); the exception is thrown because the product is not loaded.

When enable_lazy_ghost_objects is false, the proxy has a method to initialize the product entity on getTranslation() call.

When enable_lazy_ghost_objects is true, the proxy does not intercept the function call and the object is not loaded.
I must call a getter manually to force the object data loading before call getTranslation().

Possible Solution

Check if the object is initialized and try access to the translations property to force data loading.

Work when I add this code into vendor/sylius/resource-bundle/src/Component/Model/TranslatableTrait.php line 50

        if (!isset($this->currentLocale)) {
            $this->getTranslations();
        }
