Summary:
Moving setting `availableSize` for `RCTRootShadowView` on earlier stage allows to prevent situations where `availableSize` is not specified yet, but Yoga layout is already happening.
Because `availableSize` equals {infinity, infinity} by default (in this case), Yoga returns a lot of nodes with infinit metrics, which confises UIKit.
