Break test order dependencies in security-rules integration tests. (#673)
Break test order dependencies in security-rules integration tests. (#673)

Previously, this would work:
yarn test:integration --updateRules --grep 'admin.securityRules'

but this would not:
yarn test:integration --updateRules --grep 'admin.securityRules.getRuleset\(\).rejects with not-found'

because that test relied on side effects from earier tests, making this
test suite difficult to debug.
