The displacement Tribol sees is usually changed after calling
nonlin_solver_->solve()and this displacement doesn't necessarily match the final displacement at the converged solution (e.g. if the residual is already at 0, TrustRegion will put NaNs in for displacement). This fix just resets the displacements to the value returned by the nonlinear solver, ensuring thecontact_.update()call sees the right values.
