Regression fix: not purged object is not purged after 'purge --local'

call_action -> self.setup_environ -> os.environ['OPENSVC_SVC_ID'] = self.id -> create object if object is absent and not self.volatile

So after purge/delete action the object is recreated

The regression was introduced by #817b97660894971e18689393c6090d1a57a901c6

Reproduce bug with:
   om foo create
   om foo purge --local
   om foo ls
