Missing extra-user-roles=admin profile

[taurus-forever]

Steps to reproduce

juju deploy mysql --channel 8.0/edge 
juju deploy data-integrator
juju config data-integrator/leader extra-user-roles=admin
juju relate mysql data-integrator
juju wait-for application mysql
juju run-action data-integrator/0 get-credentials --wait
charmed-mysql.mysql -h 127.0.0.1 -u<user_from_above> -p<pass_from_above>

Expected behavior

You should see all databases (including mysql, as you are now root).

Actual behavior

You see only DB created in relation + information_schema + performance_schema
