When EB module is uninstalled, it removes the authenticated role.

I've just hit this issue on a site. We uninstalled EB and switched to media library. Any role that contained EB permissions was deleted and recreated on config import, which meant that any users who had the role lost it.

I haven't investigated yet but sounds similar to 🐛 Roles can be deleted when upgrading from 9.5 to 10 if a module had removed permissions Active ? Although in this case it wasn't removing non-existent permissions. The previously granted permissions are valid, they just are for a module that is uninstalled.

On trying to reproduce from scratch, I did get a warning that the role would be deleted:

So maybe I ignored the warning on the first pass.
