Missing "class" config key on Laminas Mezzio

[Rodrigo Teixeira Andreotti]

Hi!
I'm facing some initialization problems with lib.

The exception that I receive is:

ServiceNotCreatedException
Service with name "doctrine.entity_manager.orm_default" could not be created. Reason: Missing "class" config key

My global config:

return array(
    'doctrine' => [
        'driver' => [
            'orm_default' => [
                'class' => \Doctrine\ORM\Mapping\Annotation::class,
            ],
        ],
        'connection' => [
            'orm_default' => [
                'charset' => 'UTF8mb4',
                'collation' => 'UTF8mb4_unicode_ci',
            ]
        ],
        'configuration' => [
            'orm_default' => [
                'result_cache' => 'custom_cache',
                'metadata_cache' => 'custom_cache',
                'query_cache' => 'custom_cache',
                'hydration_cache' => 'custom_cache',
            ]
        ],
        'cache' => [
            'orm_default' => [
                'custom_cache' => [
                    'class' => CustomCacheProvider::class, // Because Doctrine Cache breaking changes
                ],
            ]
        ]
    ],
    'dependencies' => [
        'factories' => [
            'doctrine.entity_manager.orm_default' => \Roave\PsrContainerDoctrine\EntityManagerFactory::class,
        ],
    ]
);

Edit: With some debug i found that problem is with cache factory, maybe related with #46

It's possible to disable cache for now, while I'm in developement time?
