Fix widget restore for pre-archived apps

Widgets which were expected to be restored, were missing for apps which were pre-archived.
The fix adds checks for archived apps when processing widgets and ensures that icon with cloud overlay is present on the widget.

Test: Flashed device with build containing this fix.
