Properly set all data fields

So stale data doesn't stick around when the view is recycled

Test: manual:
- dismiss a notification
- set a short timer (a custom view notif)
- check history after timer expires (so there are 2 notifs in 'recently
dismissed')
- stop the timer and check history
- there are now 3 notifs and no stale text in any of them
