Streamed response headers are case sensitive

[GithubUser8080]

When the request has .streamed(), then all methods to get headers, like response.getContentType() fail if the case is not an exact match. E.g for response Content-Type : application/json, response.getContentType() returns octet-stream. It only succeeds if the headers are all lowercase. Normally header matching must be case insensitive.

@GithubUser8080 Just taking a quick look, maybe this line could be related?

play-ws/play-ws-standalone/src/main/scala/play/api/libs/ws/StandaloneWSResponse.scala

Line 73 in 1f4f1d1

def contentType: String = header("Content-Type").getOrElse("application/octet-stream")

I will try to remember the exact line, but if i remember correctly, all other response types, when getting headers, return a TreeMap copy of headers with case insensitive keys. Whereas StreamedResponse getHeaders() returns the original case sensitive map of headers from the underlying response.
