[CRASH] Another attempt to complete a future more than once.

[benbierens]

Seen in v0.2.5 in multiple of the auto-client uploader/purchaser nodes. These are not configured with prover nor availabilities.

Located at started.nim:32

  let failed = newFuture[void]()
  proc callback(_: RequestId) =
    failed.complete()

Looks very similar to the previous one.
