Changelog

### Changed
 - Load mapping earlier (priority 10)

There is a problem if you want to the the doctrine extensions together with gedmo sluggable, because both loadClassMetadata event listener will run at the default priority (0).

---

The problem can be reproduced when defining a mapping using sonata:

        $collector = DoctrineCollector::getInstance();

        $collector->addAssociation(
            'role_table',
            self::MAP_MANY_TO_ONE,
            OptionsBuilder::createManyToOne('topic', 'topic_table')
                ->cascade(['persist'])
                ->addJoin([
                    'name'                 => 'topic_id',
                    'referencedColumnName' => 'id',
                    'nullable'             => false,
                    'onDelete'             => 'CASCADE',
                ])
        );

and having a entity mapping:

namespace App\Entity;

class Role {

    #[Gedmo\Slug(fields: ['name'], updatable: false, separator: '_', unique_base: 'topic')]
    protected ?string $slug = null;

   // ...
}

You receive an error:

  Unable to find [topic] as mapped property in entity - App\Entity\Role
