rigidbody: Fix motion paths calculation being incorrect for rigid bodies

Browse Source 
For the simulation to work properly the limited update the motion paths
calculation did wasn't enough so you got different results for for
motion paths than for the actual simulation.
Now do full frame update if rigid body sim is active.

TODO investigate if we can still limit this.
