Update numeric-hour-with-zero-minutes-and-non-zero-seconds for new default display of sub-hours units

Numeric "minute" and "seconds" units now default to "always" display, so we have
to add an additional test to cover when "auto" display is used. Additionally add
more inputs to cover all possible test combinations.
