Notification testing output should be more inclusive and consistent.

Notification testing output should be more inclusive and consistent.

consistent with the other messages, and adds the "tag" value to the
NOTIFICATION SHOWN message. "lang" should be added as well.

Address a minor TODO about clearing local values as well.

closing notifications. It also gets rid of the weirdly formatted section in
NotificationPresenter::show().
