Fix flagToReturnFailedTrack warning (ATR-23846, ATR-24827) for disappearing track trigger (ATR-21590)
- Failed tracklets were not used in disappearing track trigger due to wrong order of initialization of track object in FastTrackFinder
- This MR will change counts and EDM sizes only for disappearing track trigger (although with ART test (runTrigART.py) no trigger count change was seen in limited data statistics).
