In case you guys were unaware, I noticed that the demo for BoneIKController is broken in Latest. It works in v5 and v4.

See https://forum.babylonjs.com/t/boneikcontroller-demo-broken/43211 This bug… appeared after my changes to the bone class because `BoneIKController` relied on a bug in the old `Bone` class, where the absolute transformation matrix had a value, but a wrong one - it contained the absolute bind matrix instead of the absolute matrix! To make sure we get up-to-date absolute matrices, we need to call `skeleton.computeAbsoluteMatrices()`.
