Add some tests for justification under row-reverse (#1560)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1560

I added these when I was trying to debug the Facepile break removing the row-reverse errata caused. Yoga is doing the right thing, and the tests pass. We didn't have this specific coverage before, so add it.
