When changing a product's attribute in the add to cart form, a secondary attribute will not be visually updated to reflect that it's checked even if it's the only option.
This may be due to the ajaxRefresh call or the renderer of radio buttons in drupal.
The commerce functions seem to return the correct values and defaults. Still no `checked` element is rendered on the attribute after the ajax call.
Unrelated to the active theme, has been tested on both the default and custom themes.

Hi,
I've implemented the fix in ProductVariationAttributesWidget. During an AJAX refresh, if the selected radio button from user input doesn't exist in the newly rebuilt #options, we just select the first radio button as fallback.
Please review and confirm.
