certbot fails when called with --no-passphrase and --non-interactive

[augjoh]

When calling certbot with --no-passphrase and --non-interactive it fails during PFX creation:

$ python3 cli.py cert --no-passphrase --config-dir . --work-dir . --logs-dir ./logs -e address@mail --contact contact@${HOSTNAME} --imap --host mail --port 3143 --agree-tos --login address@mail --password address@mail --host mail --smtp-port 3025 --smtp-host mail --non-interactive

Skipped user interaction because Certbot doesn't appear to be running in a terminal. You should probably include --non-interactive or --force-interactive on the command line.

An unexpected error occurred:
