Talkback would previously report nesting level for single-level lists,
which was considered unnecessary. Added functionality in the
IsHierarchical() method to determine if a list contains other lists,
or if it is contained within a list, to help determine if it is
hierarchical. Also modified DumpAccessibilityTree test expected output
files to check for new desired behavior.
