PDFViewer: Create OutlineModel items with the correct pointer

Browse source 
This fixes a bug where we would construct a ModelIndex with a pointer to
NonnullRefPtr<OutlineItem>, instead of a pointer to the underlying
OutlineItem, which caused a crash later on when we would try to
dereference that pointer.
