Hi - Can you write a test for this?

[wvanderdeijl]

@vikerman tests have been added. I've added one test that simply does a .map over a lot of elements. It has to be a large number of elements as it is a race (concurrency) issue. With this many elements it consistently fails with ChromeDriver on MacOS.
The second test simply verifies the implementation no longer uses a Promise.all (with concurrent requests), but that the promises should be chained (thus serial requests)
