Test showcasing query string behaviour as described in issue #1586

As described in issue #1586, when using Internet Explorer together with Python3, and the query string contains raw UTF-8, the request will fail if it's sent through DRF.

Internet Explorer handles query strings very weird, as described by http://stackoverflow.com/questions/18220057/encoding-of-query-string-parameters-in-ie10 - in general, one cannot expect internet explorer to urlencode it's query strings.
