Remove return type declaration to Interceptor classes

[thedotwriter]

Hi,

Since 1.4.2, you've added return type declarations pointing to Interceptors. You probably meant to use Interfaces.

As an example, you've added return type declarations ?ProductInterceptor (Magento\Catalog\Model\Product\Interceptor) to :

• \Lengow\Connector\Model\Export\Product::getProduct
• \Lengow\Connector\Model\Export\Product::getParentProduct
• \Lengow\Connector\Model\Export\Product::getConfigurableProduct

Please, use \Magento\Catalog\Api\Data\ProductInterface instead. Otherwise, everythings breaks when a module applies a preference on the Product model.

Error on the export process:

TypeError: Return value of Lengow\Connector\Model\Export\Product::getProduct() must be an instance of Magento\Catalog\Model\Product\Interceptor or null, instance of DialogInsight\DI\Model\Override\Catalog\Product\Interceptor returned in /path/to/website/vendor/lengow/module-connector/Model/Export/Product.php:556

You don't use it in the code but it's the same issue with all occurences of StoreInterceptor. You never have to call any Interceptor class yourself.
