Daemons - add "objectPHID" to task tables.

Summary: Ref T5402. This more or less "fixes" it but there's probably some polish to do?

Test Plan:
stopped and started daemons. error logs look good.

ran bin/storage upgrade.  noted that `adjust` added the appropriate indices for active and archive task.
