Notification testing output should be more inclusive and consistent.

This patch makes the testing output for notification layout tests more
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.
