Subject: [PATCH]  updating componentwillreceiveprops so that it is flexible
 for a usecase where youre updating the props passed down to a child state
 (i.e. you favorited a card and added to parent state and you're passing down
 that state to child as a prop) after an action and you dont want the cards to
 restart
