Use `Task.Run` to start `OperationQueue`'s processing task rather than using
the constructor and then calling `task.Start`. This ensures two things:

1. The `TaskScheduler.Default` scheduler is used, which will be a threadpool

will have completed when it `await`ed as the `Task` constructor accepts an
`Action` and not a `Func<Task>`
