fix(learner): don't record other players' kill positions

On PARTY_KILL and unengaged kills, the learner was recording the local
player's position (GetCurrentPlayerPosition) as the spawn location.
This polluted the learner's spawn map with the wrong coords. Now only
records position for credited kills (your own kills or mobs you damaged
within the last 60 seconds).
