remove "ignored" test
remove "ignored" test

636eade4355ec5e8ed40e434f25cfcf97bbc843d attempted to ignore a test for
windows, but it added the `runtime.GOOS` check inside an
`Expect(... ReceivedRequests()).To(Change(By(...)))`. So, since we short
circuit on windows, the received requests doesn't change at all.

Moreover, a later commit in the PR #5861
(71305ef18c233c3e44fb00288195f39ed64d430d) removed the "ignore windows"
behaviour - so we should just get rid of the `runtime.GOOS` check
altogether.
