• Changed constructor of Shopware\Core\Checkout\Cart\Event\CartMergedEvent to accept a previous cart.
• Added method Shopware\Core\Checkout\Cart\Event\CartMergedEvent::getPreviousCart().
• Changed method Shopware\Core\System\SalesChannel\Context\SalesChannelContextRestorer::mergeCart() to provide the CartMergedEvent with the previous cart and not clone errors
