SkipEventException handling does not work?

[Zehvogel]

New issue for the leftover case from key4hep/k4FWCore#156, reproduction info is there

It looks like MyConformalTracking finds to many tracks and the event loop then terminates in event 914. With edm4hep output this causes the same crash as in the issue above, with lcio output the log looks like this:

It looks like the handling for this case does not work as intended looking at the line
