Fix tau hypo configurations

Trying to remove spurious selections applied after preselection step for tracktwo and track chains. Also removing selections applied after fast tracking (core, iso and isobdt) steps, all of these were not applied during Run 2 (AFAIK) I think this changes could also fix the phi modulation and other weird ET distributions seen during validation checks ATR-22883. I'm attaching HLT_tau25_mediumRNN_tracktwoMVA Run 2 chain configuration
