The SAC uses the AuthorizedToMaintainLiabilitiesFlag to deauthorize a trustline. If a trustline is completely deauthorized (AuthorizedFlag and AuthorizedToMaintainLiabilitiesFlag are both not set) and you call the deauthorize function from the SAC on it, the SAC will set AuthorizedToMaintainLiabilitiesFlag. This PR makes that scenario (as well as authorizing an authorized trustline) a noop for the auth flag state.
