The shadow entry for a password disabled root will be '*:::::::'. This is to avoid the root user getting disabled due to password requirements. Also added a CI unit test. Also fixed a small error in the unit test. Reporting info on an assert was missing some data.

When user passwords are disabled the user can no longer manage password change requirements or any password policy restrictions. Under certain configurations, e.g. STIG, this can lead to the user account being disabled. We want to avoid this condition.
The fix for this is to special case the user shadow entry to disable all expiration type settings when the user has password authentication disabled.
The shadow entry for a password disabled user will be
*:::::::. This will prevent the user getting disabled due to password requirements.Also added a CI unit test.
Also fixed a small error in the unit test. Reporting info on an assert was missing some data.
