## Context
For a table that has RLS enabled, but a policy with just `true` for the
role `public`
The RLS tester was incorrectly reporting that `anon` doesn't have access
Was happening as we weren't considering policies that apply to the
`public` role (which applies to _all_ roles)

access badges and policy messaging.
