Hello!

We have observed strange behaviour after mongo-driver upgrade from 2.2.x to 3.3.x.

Connection string has journal=true and it is ignored when making queries.

const connectionUri =

    'mongodb://mongo1:30000,mongo2:30001,mongo3:30002/ec?w=majority&journal=true&replicaSet=rs0&readPreference=primaryPreferred&wtimeoutMS=5000';

const client = await MongoClient.connect(connectionUri);

From the other side, using explicit `

{j: true}

` starts working.

const client = await MongoClient.connect(connectionUri, {j: true});
