[kernel] cheat a litlle bit such that the constraints are activated within the same time step 	 for this particular test. 	 With the new simulation loop with the update of the interactions at the beginning of 	 the time step, the contraint was not activated within the same time-step 	 leading to large differences in the comparison.
