BackTracker not working
Bruce reported the following problems:
It’s been a few weeks since I checked TrajCluster performance using my standard reference data set. I discovered that none of the recob::Hits were matched to MCParticles. I see that the code in TCTruth has changed a bit. The BackTracker pointer variable name changed from bt to bt_serv and there is a new pointer to the ParticleInventoryService. I find that nothing is returned from bt_serv->HitToSimIDEs_Ps(rhit).
This is in v06_58_00 after the changes to backtracker.

- Sometimes backtracker does not get SimChannel from a hit. This is fixed in larsim:81d8ead8b8cd1348b423754edc9cd9eb758fa232 and larsim:a660cff8c6cd4421934ca7eb1c065e9ca06fb02e. Related issue #18483.
- Backtracker did not take into account trigger offset. This is fixed in larsim:4c075018cf2bc6119b9b2dea914a8cfe58906c7d.
Fortunately the above two bug fixes will be incorporated into this week's release.larreco:
