Even when a notification was clicked by the user, we'd still want it to be
removed from the NotificationDatabase. In other words, //content always has to
be told about the closure.

I think what we'll want here is something like...

if (by_user) { uma_one }
else { uma_two }

content::NED->DispatchNotificationCloseEvent(..., by_user);

and then make the decision on whether or not to fire the event in //content.

[Nina, 2016/01/27 18:48:58]

Good catch - I think this became an issue when I moved the deletion code to
//content.
