Try to fix App.test.
- R1:404b01f42ea4: [dagit] Repair duplicate keys in App.test
yarn test App.test
This at least eliminates the duplicate key problem, which maybe gets us back under the timeout limit? It's weird to me that App.test does pass with this change, and it's the more correct thing to do here anyway, but I don't really know if it will repair master. 🙏
