    properties: do not require password for always-ask, not-required (bgo #756638)
    
    If password is marked as always-ask or not-required, do not insist on having a
    password.
    Actually we might detect password requirement incorrectly, because we regard
    all PKCS#12 private keys as encrypted. Thus we require a password even if
    the private key is not really encrypted. This commit allows user to override
    the bad detection.
