collection.create example

The Test:

add_task(async () => {
  info("URI sent when record is in DB");

  const collection = await client.openCollection();
  await collection.clear();
  await collection.create(
    {
      id: "tld-dafsa",
      "commit-hash": "fake-commit-hash",
      attachment: {},
    },
    { synced: true }
  );
  await collection.db.saveLastModified(42); // Prevent from loading JSON dump.

  const backup = client.attachments.download;
  client.attachments.download = async rec => {
    return mockedFileURI;
  };

  const promiseSignal = TestUtils.topicObserved(SIGNAL);
  PublicSuffixList.init();
  const observed = await promiseSignal;
  Assert.equal(observed[1], mockedFileURI);

  await collection.clear();
  client.attachments.download = backup;
});
