    Improve and finish the fallback to the In-Reply-To and References header for the reply-by-email feature
    
    A few things to note:
    - The IncomingEmail feature is now enabled even without a
      correctly-formatted sub-address
    - Message-ID for new thread mail are kept the same so that subsequent
      notifications to this thread are grouped in the thread by the email
      service that receives the notification
      (i.e. In-Reply-To of the answer == Message-ID of the first thread message)
    - To maximize our chance to be able to retrieve the reply key, we look
      for it in the In-Reply-To header and the References header
    - The pattern for the fallback reply message id is "reply-[key]@[gitlab_host]"
    - Improve docs thanks to Axil
