    NetTestController: fix url handling for python tasks
    
    The python task pathname was not handled properly if recipe was
    specified as url, e.g.
    
    lnst-ctl -d run http://example.net/recipe.xml
    
    The fix is to use abstract class RecipePath for python task pathnames in the
    recipe.
