2020R1(S5): Order Guide-Discontinue Date no longer is set to today when I delete the rule

I'm guessing something might have broken between when we did this work in CFAMX-3714 to today and in 2020R1. I'm not convinced that it is changes associated with CFAMX-7190 but could be related to the changes in the queuing of Order Guide messages. See bug CFAMX-4320.

Steps
1. Navigate to order guide for store 3700 Avalon (EntityID 4849) https://m.inform.jatesting.cfahome.com/#/Administration/MaintainOrderGuide
2. Select and Vendor code and find it in the Assign Vendor Item page
3. Delete the rule(s) associated with the vendor code and view the discontinue date

SELECT *
FROM tbVendorItemZoneRule
WHERE vendorcode = '101152'

Results: The discontinue date is not updated to today's date (the date that the rule was deleted) and the Vendor code is still available in the Store's order guide.

Expected: The vendor Entity Item should have a discontinue date of today and no longer be available in the store's order guide.
