Fix login with TOTP when multiple 2fa methods are available

[pschmitt]

If there are multiple 2FA methods available, the bw cli will prompt for which one to use. This essentially made logins impossible.

Rather than trying to fix this expect, which will surely age poorly, I implemented it using --method 0 --code TOTP_TOKEN.

@pschmitt I just tested it, and it works perfectly, thank you very much for your help!
