Joshua King 09363a57cf Review fix: race tests read via the DAO, not raw SQL probes
The children/admin_users leak guard forbids children SQL outside the
DAO and its sanctioned test files; the two gated concurrency tests
probed the children table raw. They now assert via ChildrenDao.get.
Suite: 850 passed.
