Update ash DOM agent so that widgets are direct children of windows

Small bug that caused widgets to be the siblings of their parent windows.
This fixes that by adding any widgets as the direct descendents of their
parent windows. In addition, modified the tests so that they compare
all windows to nodes. Removed the widget finding method as they can
now be queried directly from the window nodes (first child should be
the widget).
