How to test the changes in this Pull Request:

I didn't know how to reproduce using native WooCommerce features, you will need Product Add-ons extension.

1. Add a product with a priced add on.
2. Add the product to your cart, with the add on enabled.
3. See that the price is shown without a negative discount value.

Changelog

Hide the discount badge from Cart items if the value is negative.
