Title: Auto 473 assertion error fix (waiting on #275)

This fixes Auto-473, which can happen if the group is deleted before the server that was building fails.

PR is based on changes in #275. The only change on top of that is https://github.com/rackerlabs/otter/commit/4842d50c283aee4a1f12cc9506121cb1301bcda9
