Adam Comella 9304df3e3d For file uploads, don't stomp on developer's Content-Type header
Summary:
Currently when doing a file upload, the Content-Type header gets set to whatever MIME type iOS computed for the file. The Content-Type header the developer provided never takes precedence.

For example, when uploading an image, iOS might determine that the MIME type is "image/jpeg" and so this would be the Content-Type of the HTTP request. But the developer might need the Content-Type to be "application/octet-stream". With this change, if the developer provides a Content-Type header, it will not be overriden.

There is only one exception to this rule which is for "multipart" requests. In this case, the developer's Content-Type header is always ignored. This is because the Content-Type header needs to contain the boundary string and that information is not available to the developer in JavaScript.

This change makes iOS's behavior more consistent with Android's.

**Test plan (required)**

In a small test app, verified that the developer's Content-Type header takes precedence when it's provided. Verif
