Fix the pull back operation of the coupling data #65

The pull back operation of the Stress data for the nonlinear solid mechanics solver relied on the deal.II pull back operation, which is different from what we need in our case. Here, we need to apply Nanson's formula in order to get the stress in the reference frame.
