fix-cell3d-EvaluatePosition: minor refactoring
Intel compiler -O3 build produces erroneous EvaluatePosition that can be resolved by writing the loop over points slightly differently.
Common/DataModel/Testing/Python/Test3DCellsEvaluatePosition.py fails because of the issue below also for some other 3D cell types, and I fixed all of them in the same way.
