Problem/Motivation
We don't have a FakeDelete class.
Proposed resolution
Copy the FakeUpdate class to FakeDelete, change the array_walk to array_filter and that's approximately it. These fake things don't really have a test so I have attached a meld screenshot to show how little the difference between the two is. I also tested this manually.
Remaining tasks
User interface changes
API changes
