Auth delete should delete whitelisted IPs

When we delete auth on site with `ee auth delete `, we also expect that the site's whitelisted IPs will also be deleted. They don't get removed and we have to remove it manually with `ee auth delete --ip`.

Now we have to ensure that Whitelisted IPs also get deleted with `ee auth delete ` and we don't have to delete them separately with `ee auth delete --ip`.
