This pull request modifies the logic of
DefaultCustomPhaseto update the best solution when the returned solution is not better than the starting phase one.When the planning list variable accepts unassigned list values, the custom CH does not update the best solution because it may be possible that it does not improve the starting score (
0hard/0soft).
