[Bug]: Creating offer from cart throws error

[GAL-CS]

Expected behavior

No error is thrown.

Actual behavior

An error is thrown:

Pimcore\Model\DataObject\OfferToolOffer::setCartId(): Argument #1 ($cartId) must be of type ?string, int given, called in /var/www/html/vendor/pimcore/ecommerce-framework-bundle/src/OfferTool/DefaultService.php on line 84

Steps to reproduce

Call createNewOfferFromCart in https://github.com/pimcore/ecommerce-framework-bundle/blob/1.x/src/OfferTool/DefaultService.php#L78.

When this function wants to store the cart ID on the offer, an error is thrown because $cart->getId() can also return an integer, but $offer->setCartId() only accepts null or a string. (https://github.com/pimcore/ecommerce-framework-bundle/blob/1.x/src/OfferTool/DefaultService.php#L84)
