Update to post_process_elem_matrix_and_vector in RBConstruction
Update to post_process_elem_matrix_and_vector in RBConstruction

We should only call post_process_elem_matrix_and_vector if apply_dof_constraints
is true because we want to be able to compute matrices with no dof constraints
or dof transformations included in them.
