Issue

Title and steps come from the upstream issue and pull request.

Description

Skip any deleted/invalid custom options instead of including them in the result

2. add to cart products A and B
3. remove custom options from product A or B
4. attempt to get the cart using graphql

  cart(cart_id: "xxxx") {
    items {
      ... on SimpleCartItem {
        customizable_options {
          label
          values {
            label
            value
          }
        }
      }
    }
  }
}
