The FindWhereSleepController in allow_partial_results_with_maxTimeMS.js assumes that find will return documents in _id order, and that tends to happen when testing locally, but that's not guaranteed by WiredTiger. We should add a .hint({_id: 1}).

Also, ampleTimeMS was recently changed from a minimum of 2 seconds to just 100ms. This appears to be too short, and the change corresponds to the appearance of BF-26974. This timeout change should be reverted.
