request_id only shown when exception is raised

[ivica-k]

Hello and thank you for the library. I'm currently using version 0.10.1 and I'm having an issue that the header X-Request-Id is only visible in the werkzeug logs if an exception is raised. I've created a small working example that shows what I mean; you can clone it from https://github.com/ivica-k/request_id_example

Let me know if I can provide any more information.
