[xmlparser] Remove re-setting of object attributes

XMLReader.parse_tag contained code re-setting attributes
of previously instantiated odML objects. This code has been
made obsolete by previous rewriting of the instantiation
method and is potentially harmful by circumventing
instantiation attribute checks. It is therefore removed.
