Can't push again to reset repository

If I:

1. Create a new repository on Language Depot
2. I can push to it with resumable 👍
3. I reset the repository on Language Depot
4. When I try to push again it fails 💥
5. I delete C:\ProgramData\SIL\FieldWorks\Projects\sena-3\Chorus\ChorusStorage
6. I can push again 👍

So, it seems that the cache on the client somehow leads to confusion on the server.
I presume the server is at fault.

Here's the relevant part of the logs

and a trace:

Start with the logged pullBundleChunk API request and the client cache at C:\ProgramData\SIL\FieldWorks\Projects\sena-3\Chorus\ChorusStorage. Reproduce the failure by resetting a Language Depot repository and pushing again, then compare behavior before and after deleting that cache. Done means a reset repository accepts the subsequent push without manual cache deletion and the timeout is resolved.
