Network Manager overrides saved password with 2FA temporary code

[Andrew Mantha]

Set up OpenVPN with MFA.

Connect, and enter MFA code when prompted.

Disconnect and reconnect

Expected: Password portion is saved and reused

Actual: The MFA code is saved in the password field and attempted first, then prompted for PW.
