Steps to reproduce:
1. Delete search index (on a non empty database)
2. Restart matterhorn; wait for index to rebuild
3. On completion go to the media module - all dates appear as n.a.
Media module dates appear as n.a.
/search/episode.json endopint shows no dcCreated entries
The dates should appear as they did before i.e. the index should rebuild successfully
Workaround (if any):
rebuild the index by deleting it and restarting the search service implementation via the system/console
