Add logging for notifications.

- Log notification launches
- Log notification swipes
- Fix logDragNDrop() to only log if the pre-drag ends (so it doesn't
  log a long-press that only shows shortcuts without dragging).
- Add shortcut rank to logs when launching deep shortcuts, where 0
  is the shortcut closest to the app icon (highest rank).
