a11y: Report app as parent for top-level item views

Browse Source 
As happens for other widgets
(s. QAccessibleWidget::parentObject), report the app
as accessible parent for item views that don't
have another parent set.

Otherwise, the accessible tree is broken when
there's a top-level item view:
The application has the item view as a child,
but the child does not have any parent set.

Extend a QListView autotest accordingly.

Fixes: QTBUG-115135
