db provisioning fails because of missing public.auth_user table

[paolantoni]

Please add a test to check the database integrity task after creation because the task that set privileges fails. It' s hard to understand why the database is empty and which role had not effect on ansible invocation.

TASK [driver.access : Set table-level access privileges for Windshaft DB role]
fatal: [database]: FAILED! => {"changed": false, "msg": "relation "public.auth_user" does not exist\n"}
