Before this patch, test_logins_decrypt_failure.js would essentially call
PK11_ResetToken and then PK11_ChangePW (via nsIPK11Token.reset and
nsIPK11Token.changePassword, respectively). This was never correct (after
PK11_ResetToken, the token has no password, so it can't be changed), and after
bug 1379273 this actually fails. The correct thing to do is PK11_ResetToken and
then PK11_InitPin (nsIPK11Token.initPassword).
