As discussed in https://github.com/mongodb/mongo-php-library/pull/643#discussion_r307111324, the tests on how to handle readConcern in aggregation pipelines with $out only cover the aggregate helper on the collection object. Since database-level operations shouldn't need a readConcern, tests should be added to ensure consistent behaviour of the aggregate helper on the database object across drivers.
