Use UnpackTrackFunctional in PersistRecoConf
Using UnpackTrackFunctional in PersistRecoConf allows to deduce data dependencies without hacks.
Fixes issue reported in Moore!924 (merged) .
Also added DataHandles to UnpackTrack which is the non functional version. I guess it is still used for unpacking of Muon tracks.
Requires Rec!2500 (merged)
