Issue Description:

When using an OperationQueue with the “pure” Swift Foundation, if the queue contains an asynchronous Operation, the waitUntilAllOperationsAreFinished method will not wait for the asynchronous operation to be over.

This is demonstrated in this project:
https://gitlab.com/frizlab-demo-projects/swift_operationqueue_test

To test, simply clone the project, and run swift run on a Linux machine. One test fails (testAsync).

I can add a unit test and make a pull request to Swift Foundation if needed. I’ve read the code, and to me it seems the implementation of the OperationQueue is to blame here.
