When a shift is Split, original shift not "lost"
Entered on behalf of Envoy, see RAPD-6623.
When a Crew Scheduling shift is traded away, the original employee should have COM added to their timecard in place of the original shift.
When a shift is thereafter split on the recipients end, the COM leaves the giver's calendar.
This is because when the shift is split, the original shift is lost.
Customer would like to recommend that shifts are not lost when split.
