Subject: [PATCH] Fix mistake in swapping left/right layout properties

Summary:
Changelog: [Internal]

We were assigned `undefined` value to incorrect edge, instead of `YGEdgeLeft` it should have been `YGEdgeRight`.
If node has `YGEdgeRight` value, it needs to be reassigned to `YGEdgeEnd` and its original value set to undefined.
