Updating ItemInfo objects in the worker thread

> Launcher was making non-trivial updates to ItemInfo objects
on UI thread. These updates were getting skipped when the
Activity gets destroyed (possibly due to onConfigurationChange)
> Unregistering SessionCallback on application onTerminate,
rather than activity onDestroy
