Updated migration 36 (checked in with the last changeset) to initialize existing completed projects with a reasonable completed_at date. If you've already migrated after updating to the last changeset, you can do the following:

rake db:migrate VERSION=35
 rake db:migrate
 
If not, you can just migrate normally. Thanks to lrbalt for the catch. Reclosing #550.
