Subject: [PATCH] #slug should not default to _id.to_s. This is inconsistent
 with the rest of the gem: - _slugs does not contain _id.to_s - clear_slug!
 sets slugs to [], so #slug will return nil in this case - it will be
 overwritten when saving - before saving, one would expect both slug and
 _slugs to be nil
