Acording to this issue: https://jira.mongodb.org/browse/NODE-1911 it should be fixed, but submitted PR just adds single test to `collection.updateMany` method in `test_bulk.js` file which is another issue.

Looks like `BulkOperationBase` class can handle `arrayFilters` via `raw` method: https://github.com/mongodb/node-mongodb-native/blob/master/lib/bulk/common.js#L880 but there is no `arrayFilters` method whatsoever.
