Do anything else before expectedly failing role creation
Creating roles during database setup expectedly fails in case there
already is another gemma database in the cluster. Doing it at the end
of the transaction ensures it does not hide errors in other commands
in the script.
In passing, add the default admin via the designated view to ensure it
will become a correctly set up application user.
