authPrompt: fix disable-user-list / Not Listed?

Browse Source 
If the first question asked to a user is from the
shell and not from the PAM service (i.e. Username: ),
then we'll save what the user types until PAM asks
a question and then try to send it to PAM.

This commit makes sure the preemptive answer can be used
before the PAM conversation gets started, and makes sure
to discard the preemptive answer if we're not expecting it.
