Call updateLayoutBounds on NestedArtboardLayout

I think this is the right fix here. Since the calls to updateLayoutBounds are now passed down through layout children rather than on advance, we also needed to call updateLayoutBounds on NestedArtboardLayout, since those "provide" their layout nodes to their parent artboards layout tree (thus updateLayoutBounds doesn't get called during their own Artboard's advance).
