VehicleJourneysController: When filtering departure_time allow nil stops

There's a `params[:q][:vehicle_journey_without_departure_time]`
parameter coming in from the frontend that's supposed to allow it to
decide whether or not to include vehicle journeys that have nil stops.

Allow this parameter to function for the
`VehicleJourney.where_departure_time_between` method by conditionally
checking an input parameter to determine whether to add the "OR"
condition onto the "WHERE" filter.
