Deployment: bug fix related to removing spaces

We deployed yesterday to fix a bug reported by Andy Reynolds, where we were not correctly recycling primitives (e.g., benchmarks) when a user requested we do so when removing a space. What was happening is that we were accidentally just orphaning the space, which left references to the primitives still (in the orphaned space), so the primitives were not being removed. We have fixed this now, and retroactively removed all spaces we accidentally orphaned. This means that you may find you have recycled primitives now, on your profile page.
