Bug 13871: [QA Follow-up] Adjust Patron Info Request

 Bug 13871: [QA Follow-up] Adjust Patron Info Request

Conform QA comment, Patron Info request is slightly adjusted to be
consistent with changes to Patron Status request.

If the cardnumber is ok and the password is wrong, BL=N is reported but
also add 'Invalid password' in AF.
Additionally, an invalid card number is reported in AF.

Test plan:
[1] Send patron info request for invalid card.
[2] Idem for valid card, no password.
[3] Idem for valid card, good password.
[4] Idem for valid card, wrong password.
