fix(fsproductindex): Fix infinite loop of requesting reviews

Since the requestReviews method now alters the component's state rather
than triggering an update that results in new props being passed in, the
props/state commerceData in getDerivedStateFromProps were never equal.
This caused the subsequent componentDidUpdate call to always request a
new set of reviews.
