Method fromCachedConfig should only load config

[sandrokeil]

The method fromCachedConfig should be split up. It should only load the config and after that, the initialize() method should be called like for the normal initialization. For instance if the $eventQueue parameter is an instance which relies on event engine itself it can only be created via proxy manager.

    public static function fromCachedConfig(
        array $config,
        Schema $schema,
        Flavour $flavour,
        EventStore $eventStore,
        LogEngine $logEngine,
        ContainerInterface $container,
        DocumentStore $documentStore = null,
        MessageProducer $eventQueue = null
    ): self {
