Fix for issue #1074 - SSE Supernova records duplicated

[ilyamandel]

Yikes. I'll approve, but this business of stashing info, delayed writing, and having to occasionally clear stashes looks very susceptible to future issues where someone forgets to clear a stash (I certainly would have). I am not suggesting that I know a cleaner way, but I think this is primed to bite us again.

I agree @ilyamandel. The reason we stash and delay the write is because of the (COMPAS) SSE method of evolving and reverting if we decide we evolved too far - if we write directly to the file we might have written a record when we decide to revert, so we'd have to go and remove that record - easier to stash and delay the write. I'm hoping the c'ear stash' problem will be obviated with the work to resolve the COMPAS vs Hurley sse differences.
