ISF_Event/ISFTruthIncident: implemented childBarcode getter, enhanced unit test coverage
ISF_Event/ISFTruthIncident has bugs and deficiencies. These block fixing memory leaks in ISF_FATRAS.
This MR addresses the following deficiency:
- childBarcode getter had a dummy implementation, returning 0. I replace this with a valid childBarcode.
- I test the change with ISFTruthIncident unit test, which I also update to enhance coverage
The only client of ISFTruthIncident's childBarcode is ISF_Services/TruthSvc.cxx. I tested this client will yield same results as prior changes, as detailed below.
