ConfigItem: use getTree also inside the RemoveChangesListener() method

This is the only method which accesses the m_xHierarchyAccess member
directly (except getTree() method). All other methods are using
getTree() to access it.
This direct member usage might be a problem when the code is run in
fuzzing mode or the constructor is called with ReleaseTree mode.
