Simplify the code again.

We do not need `isVerificationStatusKnown`. If `sessionVerificationService.sessionVerifiedStatus` is `Unknown`, `isSessionVerificationStateReady()` will return true and `isSessionNotVerified()` will not be called, since the `ftueState` will be `FtueStep.WaitingForInitialState`.

Note that TU is still OK with this change.
