IE9 returning 1223 for HTTP 204 no content

[dagda1]

I've just upgraded to 0.11.1 and noticed that our IE9 api requests that return 204 are now noticeably failing. This is because of this bug.

It turns out they were always failing but the old code was returning Promise.reject(data) instead of this update.

I was going to submit a PR to fix this but I want to first check that you would entertain a bug fix for IE9. It is sadly on our list of supported browsers and is not up for removal

Hi @dagda1 I of course accept this PR. Welcome))
