When we need to reindex a Work, we delete a WorkRecord for that book. A script runs periodically and reindexes all Works that don't have the corresponding WorkRecord.

We need a similar script that makes sure all Works have up-to-date presentations. Whenever something happens that causes a large number of Works to have their presentation recalculated, we should be able to delete a bunch of WorkRecords in a migration script and let the script run in the background, chugging away. Currently we have to recalculate the presentation for one work at a time.
