Repro steps:
1. uncomment the flower section of the docker compose
2. start augur and wait for it to be up
3. go to localhost:5555 or whatever the flower port is
4. observe tasks being processed on the workers tab
5. click the title of any worker
6. observe error
7. go back
8. click that same worker again
9. observe no error

The error in question is just a blank page with the flower navbar that says:
```
Unknown worker 'frontend:e7a9148f6a8b4aaeb798fe16178e1d73@52d73f41da4c'
```

steps 5-9 can be repeated once for each worker in a given startup.

Why does it do this?
