[unity] Fixed initial animation not being mixed out in some circumstances due to PoseSkeleton call. Removed PoseSkeleton and PoseWithAnimation extension methods to prevent related issues on user side. Fixed incorrect random Nth frame preview in Scene view for SkeletonAnimation and SkeletonGraphic. Closes #1340.
