6909: Gedcom export adds birth place/date in death

_remaining_events method did the _dump_event_stats indiscriminately,
even if the event in question was skipped during processing as
a birth/death one. Moving the call into the _process_person_event
thus aligning the logic with _remaining_events's docstring.
