Valid Content-Type header are eaten-up by headerValueByName directive

It seems that HeaderValueByName, optinalHeaderValueByName and headerValueByType are not returning the content type if it is an valid one.

I posted already something on the mailing list https://groups.google.com/forum/#!topic/akka-user/ZClckCsc8e4

For testing purpose I wrote a small server (to test my client) object WebServer extends HttpApp { def route: Route = path("publishvalid") { optionalHeaderValueByName("Content-Type") { header => println("Content-Type is "+header) post { complete("") } } } }

While doing this I observed that the directive optionalHeaderValueByName was never returning a valid value if the Content-Type I send was valid (I used postman for it). If I used a customized Content-Type it works fine. Observed the same fore headerValueByName and HeaderContentType.

This seems like an bug for me, evenso it is mentioned here http://doc.akka.io/docs/akka-http/10.0.4/scala/http/common/http-model.html#http-model that the Content-Type is treated differntly.
