Fallback to non-skeleton Header (#416 )

Sometimes my collectionview's header doesn't need to be 'skeletoned' while the content does. When collectionSkeletonView(_ skeletonView: UICollectionView, supplementaryViewIdentifierOfKind: String, at indexPath: IndexPath) -> ReusableCellIdentifier? returns nil, it's best if we fallback to the non-skeleton header.
