Fix a bug preventing nginx from being reloaded after generating a cert

Change the notifies property to :immediately in nginx_certbot_site. This
way the vhost template is recreated and then triggers a reload of the
nginx service. The previous code resulted in nginx not being reloaded,
as the action had already been queued earlier.
