NODE-3767 Description

What problem are you facing?

Trying to connect to mongodb+srv://username:password@somecluster/somedb?replicaSet=some-replica-set&connectTimeoutMS=10000&authMechanism=SCRAM-SHA-1&authSource=admin

The DBName is deleted because authSource in the URL exists, which results in the default dbName of the MongoClient to be set to "test". Removing authSource from the URL fixes the issue.

Apparently this was introduced in this commit: https://github.com/mongodb/node-mongodb-native/blob/ac445991a48b1c7b7a436a71fdad67c7b1cf9d4a/src/connection_string.tshttps://github.com/mongodb/node-mongodb-native/blob/main/src/connection_string.ts#L294

What driver and relevant dependency versions are you using?

4.2.0

Steps to reproduce?

 
const client = new MongoClient(mongoDbConnectionUri, this.options);
const db = client.db()
 
Any operations on db will always use 'test' as database name.
