create_slurm_accounts.py erroring out at startup if sacct not enabled.

[gwolski]

Using default set up for accounting, I have not enabled/added anything to /opt/slurm/config/accounts.yml.
If cluster is not yet enabled with sacct, the program runs, but errors out.
you can see this in /var/log/slurm/create_slurm_accounts.log:

I have the users created with the users_create script, and json file exists, but I hadn't enabled accounting yet.
once accounting is enabled, the program stops erroring...
