🐛(migrations) use settings in migrations

Use settings directly in migrations to avoid noop
migrations. This might have undisered side effects
if we change the config over time 'invalid' data will be
in the database.

It's a simple quick fix.
Keeping some migrations that are no useless to avoid changing
too much the migration history for users.
