36966	Test client using query_params raises ValueError when following redirect	Marc Gibbons	Marc Gibbons	"When the test client is called with `query_params` and `follow=True`, a `ValueError` is raised when following the redirect.                                                                                                 
                  
`_follow_redirect` populates `data` from the redirect URL's query string via `QueryDict(url.query)`. Since `query_params` from the original request is never reset, both `data` and `query_params` end up non-empty, triggering: `ValueError: query_params and data arguments are mutually exclusive.`
