[MOD] trackers: Another go at fixing how tracker item categories are inherited from the parent tracker. Following fixes to how perspective cateogry jails are calculated in tiki 12 (& 13) items now need to be categorised themselves, not just the parent tracker. This makes all tracker items inherit their tracker's categories by default, not just for new items, restoring category jail behaviour found prior to Tiki 12 and 13. Should better address wish4542 (thanks marclaporte)
