app_tracker: use root if there is not default label object

The at-spi2-atk does not provide 'GetDefaultLabelInfo'.
The Flutter toolkit is working on the at-spi2-atk.

If Flutter window is activated, screen-reader is not working
with the Flutter window for the '1 finger swipe'.
The screen-reader is working with deactivated window.

It is because that 'on_timeout_rebuild_navigation_context'
does not call 'view_content_changed' which calls
'flat_navi_context_setup' changing context's root and current
So the context root is not changed.

The patch is calling 'view_content_changed' using
the Flutter windowk before the at-spi2-atk provides
'GetDefaultLabelInfo' interface.
