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
     */
    pub

Describe the bug

The remove_item() method in CoCart_Remove_Item_v2_Controller has a wired condition:

if ( 0 === $item_key || $item_key < 1 ) {
    $message = __( 'Cart item key is required!', 'cart-rest-api-for-woocommerce' );
    ...
}

This will evaluate to true for some valid item keys.
