Fixed derivations names and included GenericConditionAccessor

Proposed fixes to get the follow test to run:

./run gaudirun.py Hlt/Moore/tests/options/default_input_and_conds_hlt1.py Hlt/RecoConf/options/hlt1_reco_IPresolution.py

and extra option is needed to add the FT detector to the DD4hepSvc in the options with:

from Configurables import LHCbApp, ApplicationMgr, LHCb__Det__LbDD4hep__DD4hepSvc as DD4hepSvc
dd4hepsvc = DD4hepSvc()
dd4hepsvc.DetectorList = [ "/world", "VP", "FT" ]

and we now fail with:
