Fix T38157: Rigid body, crazy f-curves after bake to keyframes

A logic error meant that the wrong "previous rotation" values were being used
when decomposing the rigidbody results back to transform channels. Instead of
using the previous values for the object in question, it was actually using
the rotation value of the previous object that was evaluated.
