Fix T68645: Hair Particle Edit - Particle Mirror crash when children are
visible in the viewport Seems to be an issue of not correctly freeing the PTCacheEdit (see T68645 for details), after discussion with sergey we went with the quick and dirty fix to free the path cache early for now. Other solution of freeing it in 'psys_cache_paths' for the non-evaluated psys [which would also fix the particle delete, then undo crash from T69000] needs more deep investigation and, possibly, reconsideration.
