cart

Improve the tier prices feature - add info like "Buy 2 in x.xx$ and save x%"

Hi,

I was trying to get the associated model from the cart item with $cartItem->model. However, it returns null.

I have seen that in CartItem class there is a call to the associatedModel function within __get method:

    /**
     * Get an attribute from the cart item or get the associated model.
     *
     * @param string $attribute
     *
     * @return mixed
     */

I'm experiencing an issue with CoCart plugin when browsing WordPress/WooCommerce backend. It breaks a critical page for another WooCommerce plugin (https://woocommerce.com/products/follow-up-emails/). An example URL of where the error occurs is:
http://example.com/wp-admin/admin.php?page=followup-emails-reports&tab=reportuser_view&user_id=123&email=john@example.com

The error trace is as follo
