Summary:
We found that `-[CALayer renderInContext:]` produces bad results in some cases (which is actually documented thing!),
so we decided to replace it with `-[UIView drawViewHierarchyInRect:]` which is more reliable (I hope).
As part of this change I completly removed support of `CALayer` from local fork of `RNTesterIntegrationTests`.
See https://github.com/facebook/react-native/pull/14011#issuecomment-303844580 for more details.
