Fix 3166

[Opt-Mucca]

This fixes #3166

I believe the error was that some data structures were not being updated when pruning in partitionRefinement. This had absolutely no effect on my run of MIPLIB 2017 with a 30min time limit. Given I'm not that comfortable with the symmetry code still, it should probably wait for a review.
