This makes sure that the tests are run on actual heap snapshots and prints out missing paths when it cannot be found, which makes failures easier to debug, and removes the unnecessary requirement for BaseObjects to be root - which would make the heap snapshot containment view rather noisy and is not conceptually correct, since they are actually held by the BaseObjectList held by the realms.
