Issue Description:

This may be a duplicate of SR-2913.

When using the URLSession dataTask method, it loses the headers I give it somewhere in between making the request and receiving them through the Kitura framework, server-side.

The problem is intermittent, but happens pretty often. I created a sample project (see attachment) that reproduces the issue, simply run swift test a few times and eventually you will see the output "Headers: nil".

Additionally, I tested hitting my endpoint in the sample project through the Postman app, and it consistently worked, with authorization headers being transmitted correctly. Thus, I'm concluding, this is an issue with Swift.

You will need to bump the packages up to run on Swift 3.0.1

    .Package(url: "https://github.com/IBM-Swift/Kitura.git", majorVersion: 1, minor: 1),
    .Package(url: "https://github.com/IBM-Swift/Swift-cfenv.git", majorVersion: 1, minor: 8)

Yes, I think with other work on URLSession and other libraries, this problem has been resolved.
