epriestley 8cb273a053 Add a unique key to OwnersPath on "<packageID, repositoryPHID, pathIndex>"
Summary:
Depends on D19181. Ref T11015. This nukes duplicates from the table if they exist, then adds a unique key.

(Duplicates should not exist and can not be added with any recent version of the web UI.)

Test Plan:
  - Tried to add duplicates with web UI, didn't have any luck.
  - Explicitly added duplicates with manual `INSERT`s.
  - Viewed packages in web UI and saw duplicates.
  - Ran migrations, got a clean purge and a nice unique key.
  - There's still no way to actually hit a duplicate key error in the UI (unless you can collide hashes, I suppose), this is purely a correctness/robustness change.

Maniphest Tasks: T11015
