Failing test when upload a file with form-data not properly merge fields arrays names

[weierophinney]

When I send a PUT method with an array and under that same name I upload an image(file) is not merged with the array that I have normal data and same name.

Thanks!

In reviewing the MultipartContentParser functionality, it appears that files are not in the body params data container; instead, when a file is encountered, it is added to the request file container (see line 265 of that class, which reads $this->request->setFiles($files)).

As such, the test needs a change in assumptions: it needs to check and see if the file exists under the equivalent hierarchy within the request's files container.
