VI Import: ROF -Deleting Vendor Item associated with a Rule, will cause an ROF on Assign Vendor Item Page

Description

This issue is probably in production.

When you delete a Vendor Item (Vendor Item Import with the 'D' Operation) that has a Rule in the Order Guide associated with it, when you open Administration -> Assign Vendor Items (aka Order Guide Page) on MxConnect, you will see a Requested Operation Failed (ROF) on the page

Workaround: is to SAFELY delete the rule(s) that is/are associated with the Vendor Item in the database:
tbVendorItemEntityRule
and/or
tbVendorItemZoneRule

Steps to reproduce
1. Add or use an existing vendor item to create a rule
2. Delete the Vendor Item associated with the rule through the Vendor Item Import
(Scenario: The vendor will no longer supply that item - Multigrain Bagels)
3. Navigate to the Assign Vendor Items page

Observe: Requested Operation Failed
Expected: No Requested Operation Failed
