Horst Schirmeier f106702d44 prune-trace: remove pilot_id from fspgroup PK
There's one fspgroup entry for every trace entry, the pilot_id is
therefore *not* part of the (unique) primary key.  If this had been
right in the first place, it would have revealed an equivalence-based
fault-space pruning bug early ... :-/
