cmssw: Error in testDD4hepFilteredViewLevel and testDD4hepFilteredViewGoTo

We are getting two errors in the unit test of DetectorDescription/DDCMS in testDD4hepFilteredViewLevel and testDD4hepFilteredViewGoTo since CMSSW_11_2_X_2020-09-27-0000, after having merged #31508. It turned out that the error is related to the hard-coded level numbers in the unit test (eg. https://github.com/cms-sw/cmssw/blob/master/DetectorDescription/DDCMS/test/DDFilteredView.goto.cppunit.cc#L73). More details in #31508. @ianna could you have a look to this issue?
