Sharding is working to remove {shardAsReplicaSet: false} from the ShardingTest fixture. We'll want to remove that test option from the auth tests. Unfortunately, this means that ShardingTest will require a journal to correctly instantiate a cluster.

curop_auth_info.js had its shardAsReplicaSet flag removed, but wasn't blacklisted from the noJournal Evergreen variant. We'll probably want to avoid exercising that part of the test on that build variant.
