Subject: [PATCH 1/2] Update apiInvoker.mustache

In scala-akka-client code that is getting generated, addAuthentication method is called after setting headers using header parameter in the below mentioned line
addAuthentication(request.credentials)(
      httpRequest.withHeaders(headers(request.headerParams))
    )

However, in addAuthentication method, we are using withHeaders method that overwrites the headers set using header parameters. So, I am proposing to
change the addAuthentication method be replacing withHeaders() method to addHeader() to add authentication header to the list of already existing headers.
