Generate the commands in the download tests, and hardcode the batch size The download tests were built on a hand-written Command repeated with a counter. They now take generated commands, with only the length of the list constrained so that it always spans more than one batch. The batch size is no longer a setting. It sits in Env at 1024, the way envHashDifficulty is hardcoded at 10, so the tests can still run against a small value without exposing a knob nobody needs.
