No longer set PatQuality in TrackV2 in PrForwardTracking
As there is plan to deprecate PatQuality in TrackV2, in this merge request, PrForwardTracking will no longer set PatQuality in TrackV2.
This change introduces a slight drop in ghost rate and a 0.03% loss in efficiency for FromB P > 5GeV Pt > 500MeV tracks. The cause for this diff is that in the current master version, UT IDs are "accidentally" used for calculating overlap between tracks, while in this newer version, only FT IDs are used
