[Fix] Check is auth prompt is undefined

[dugjason]

Should fix the error described below which occurs during kirisame init when no ORM (and subsequently no auth) is provided.
Previously code was checking for value of promptResponse.auth !== null, which is true for undefined (Thanks, JavaScript).
This should prevent the init command from crashing when selecting no ORM and no Auth 🤞
