Replicache scan never closes transaction

[arv]

Found this when performance checking... It used to work"

async function scan() {
  const start = performance.now();
  let sum = 0;
  for await (const v of rep.scan()) {
    sum += v.a;
  }
  const total = performance.now() - start;
  console.log(total);
}

Looking at the log of repm test server closeTransaction is never called.
