    XmlTemplates: do not drop toplevel aliases so that python task can see them
    
    Current implementation uses XmlTemplates to process aliases in the recipe XML
    during parsing phase. This works fine for tasks written in XML itself or
    xincluded. For the Python tasks this currently does not work since the task
    is not being processed for aliases. This patch prevents removal of available
    top-level aliases from XmlTemplates processor so that python task can access
    them via ControllerAPI during the task execution.
