Summary
Bug when approximating totals on a group caused derivs to be incorrect if a component under the group had partials declared with the 'val' argument. This was happening because groups with an approximation were still calling their linear solver during the "solve" stage of a GS iteration. Fixed by reverting to ExplicitComponent behavior when an approximation is present and active.
