 * This higher order functions take `propsAreEqual` function and

 * Normalizing in our case is making sure the `propsAreEqual` works with
 * both version 1 (object spreading) and version 2 (state object) state passing.
 *
 * To achieve this, the returned function in case of a state object
 * will spread the state object in both `prev` and `next props.
 *
 * Other case it just returns the function as is which makes sure
 * that we are still backward compatible
