[BUG] Mobile app crashes if user doen't have email.

[bhrg3se]

Describe the bug:

If the user doesn't have an email (eg root user), the org name is blank during device enrollment.
This causes the mobile app to crash if you go to the TOTP page.

This issue does not happen during enrollment of first device.
It seems the is the issue is related to /tfa API.

Expected behavior:

The API should always return org name and the mobile app should not crash when TOTP issuer is blank.
