since r42523, unrestrictedTraverse(relative_url) can raise KeyError if the object is specified as 'do nothing' when installing, so we need to do 'nothing' check before calling unrestrictedTraverse(relative_url). this change fixes current failure of test_updateBusinessTemplateFromUrl_keep_list in testBusinessTemplate.py. git-svn-id: https://svn.erp5.org/repos/public/erp5/trunk@42638 20353a03-c40f-0410-a6d1-a30d3c3de9de
