Remove direct write of Lvl1Result: unused
The direct write of Lvl1Result (i.e. evtStore->record()) is a problem for MT running. I initially changed this to a WriteHandle record, but actually I'm fairly sure we're not actually reading this anywhere downstream: it doesn't appear in the data dependencies. So it should be safe to just remove. If not, I can close this and make it a WriteHandle instead.
Will remove this warning message:
StoreGateSvc WARNING Called record() on these objects in a MT store
