    Only log application/json in session to start

    When whitelisting content types to debug print from session we chose
    application/json and application/text. application/text is not a real
    mime type, text is typically text/plain.

    Rather than guess at mime types only print application/json to start
    with, but make it easy for additional types to be added later.
