If the background color is applied via the pending state it's applied to the layer of the UICollectionView / UITableview. Unfortunately UITableView / UICollectionView does not consider using the layer backgroundColor property as it's background color, so it needs to be applied to the view after the ASCollectionNode / ASTableNode did load and the view is available

- Remove duplicated code in ASCollectionNode and ASTableNode
- Fix setting the pending state to the view if applying the pending state to the view
