Fix screen container after rnsscreen layout change. (#215)

For native stack we introduced a new way of layouting screen controllers. We no longer rely on flexbox to layout them so that we can use native stack to provide a correct dimensions and safe area paddings. Unfortunately this change broke the old screen container. With this commit we are adapting layout change to old screen container that will now layout its direct children on the native side by making them take up the whole space of the container.
