Don't modify All-Projects state in acceptance tests

We would like to reuse a running server across tests, so we shouldn't
modify All-Projects in ways that might affect later methods. Read-only
operations (e.g. listing child projects) are still generally ok, as
are idempotent modifications in setUp that are expected by all test
methods.
