    verifytree: fix handling of missing comps. BZ 1333353
    
    When we have group_command = 'objects' and no comps file, invoking
    my.comps doesn't raise a GroupsError as we would expect, and we continue
    to newrepo.getGroups() where we finally traceback.  This commit makes
    sure we detect that beforehand and fail correctly.
