DeskClock: Fix adding alarms after deletion

* When deleting any alarm and adding another (can also be via "Undo"),
  the newly added alarm rebinds the dismissed alarm
* The last state of the dismissed item was "expanded", therefore the
  now added collapsed item would rely on onAnimationEnd of the
  previously shown ExpandedAlarmViewHolder to set the visibility
* Use onRecycleItemView() which is called when an item gets recycled
  and show the items explicitely

* Test
- Add 1 alarm
- expand it
- delete it
- add another alarm
- observe: The new alarm is "empty" until you click to expand
