History/Audit trail changes if referenced items are deleted
Following situation:
Tracker A has a field that references items from tracker B.
An item of tracker A (A*) is created. The field is set to point to several items of tracker B (B*1, B*2, B*3)
The History of item A* now shows that the reference field changed value from nothing to (B*1, B*2, B*3).
Now delete item B*2
Now the History of item A* now shows that the reference field changed value from nothing to (B*1, B*3). (The same version as before)
Expectation: We need the reference for the above scenario
