Make sure request ID is calculated on every request

[acelaya]

Currently, the RequestIdMiddleware is piped for rest requests only, but the value is then ulogged for all requests, making non-rest requests log the latest generated ID, and therefore, using duplicated IDs, which should never happen.

This is not only wrong, but also, non-rest requests should also receibe their own ID for proper tracking of the tasks triggered by a non-rest request.
