Update cart doesn't trigger recalculation but only updates quantity

[fthobe]

If updating a cart only the quantities are updated.

Solidus Version:
all

To Reproduce
Change the price of a product and update a cart from the starter_frontend that already contained the product when the old price was present.

Current behavior
The old price live on inside the order line item

Expected behavior
Also the price is updated.

This is currently the intended behaviour, so this isn't strictly a "bug", but I'm open to changing the behaviour here.

I agree but didn't know which Label to pick.
