The problem is in `TestPullRequest::review`, where we will sometimes (most often) return the internal ArrayList<Review> from the underlying store object. This is causing TestPullRequest::snapshot to not return a pure snapshot, but instead something that gets updated when the store is updated, defeating the whole idea of the snapshot.

Looks good, thanks for fixing!
