Title: renaming `dbInstance` to match `db` of ReplSet and Mongos

Found the `dbInstance` property of Server to not be referenced anywhere in the code or documentation. However, both ReplSet and Mongos have a `db` property which is expected in the Db.db() function when copying `auths` to the newDbInstance.
