remove_role_if_empty doesn't work within rails console

Hi,

I am having a problem that `config.remove_role_if_empty = false` which is defined in initializer file does not work within rails console. I removed the last `user` having the role `:admin` and the role is also removed from the `roles` table.

I haven't check if remove from the web-based (rails server) yet.
