Control hashes of initial units have to refer to the empty parent set, so their combined hash is actually known a priori and can be checked early. This also changes one test that used to assume a initial unit with a broken hash can be passed into consensus.
The only connection to A0-4006 is that the test in question failed after the refactor, since I didn't want to react to this incongruous situation internally.
