Last (?) DD4HEP issue

The basic-run-mc and test_tutorial6_DecayTreeFit are the last ones failing on DD4HEP after Rec#405 (closed) and !754 (merged). There are differences in the logs:

DetectorPersistencySvc                 INFO Added successfully Conversion service:XmlCnvSvc
DetectorDataSvc                     SUCCESS Detector description database: git:/lhcb.xml

is no longer there on DD4HEP.

only appear in the DD4HEP logs.

Questions:

1. I presume the XmlCnvSvc messages should just be filtered out.
2. For the TransportSvc messages: Are we using obsolete tools? Are they replaced? It's not fully clear how Rec#326 applies.
