When queueing search index tasks, include the "objectPHID" in the task metadata
Summary:
Ref T13151. See PHI719. One minor hiccup in debugging the issue (which ended up being "revision has 100K comments") was that the `SearchWorker` did not show which object it was indexing.
Add `'objectPHID'` to the queue call so you can see which object is affected from the web UI.
Test Plan:
- Stopped daemons.
- Used `bin/search index D123 --background` to queue a search task.
- Viewed task details in web UI from `/daemon/`.
- Before change: no indication of which object was being indexed.
- After change: page helpfully shows that the task is indexing D123.
