Function getCustomOption() not working well for configurable product.

1. Magento 2.2.5: Configurable Product with Only Size Options (No Color Options) Shows No Image in Cart #16843: Magento 2.2.5: Configurable Product with Only Size Options (No Color Options) Shows No Image in Cart.

Manual testing scenarios

1. Set in admin: Stores > Configuration > Sales > Checkout > Shopping Cart: "Configurable Product Image: Parent Product Thumbnail"
2. Create a configurable product with multiple size options, but no color options.
3. Assign an image(s) only to the configurable product (not to child/simple products)
4. Visit the product page in the store front and add it to cart.

Result

Product image should show on cart page (coming from configurable product)
