Don't transfer layout outputs to java for unset edges

Summary:
See facebook/yoga#483. We should not transfer the layout if the layout didn't change. (using ```hasNewLayout```). This also changes that the lock on the java node is only aquired if needed, and it holds the lock only for the time the values are set and not for the time all it's children are set.
