Z system 17.04 guided partitioning warns about swap

During a Z system installation of 17.04 (Zesty) the guided partitioning is selected but does not define a partition for swap. This results in a warning about a missing swap partition. If the user chooses guided it's expected that a layout will be used that does not result in warnings (even if there is a shift to use a swap file). Please see the attached screen shots.
