Plan for testing:

- insert contact A
- insert contact B
- read contact B -> get contact B
- automerge (A, B) -> get expected SUCCESS result
- read contact B -> get nothing back
- read contact A -> get back merged A and B, store as $A

- insert contact C (different in some important way from A)
- read contact C -> store as $C
- automerge (A, C) -> get expected FAIL result
- read contact C -> verify C = $C (ie no change)
- read contact A -> verify A = $A (ie no change)
