Issue/Introduction

Some multi-lookup values are not being deleted after deleting an investment. 

STEPS TO REPRODUCE: 

1. Go to the Assignment object and create a Multi Value Lookup type attribute
2. Create a project, Add a team member, Create a task and Assign the team member to the same
3. On the assignment list view, pull the MVL field
4. Populate the field with some values
5. Run the following query:
   • SELECT * FROM ODF_MULTI_VALUED_LOOKUPS WHERE pk_id = xxxxxx (assignment id) AND OBJECT = 'assignment'
6. You can see the MVL values populated
7. Delete the assignment
8. Re-run the query:
   • SELECT * FROM ODF_MULTI_VALUED_LOOKUPS WHERE pk_id = xxxxxx (assignment id) AND OBJECT = 'assignment'

Expected Results: The MVL table to be cleaned out as the assignment is deleted
Actual Results: The ODF_MULTI_VALUED_LOOKUPS table still holds records
