Middleware should be applied to unimplemented APIs

[mutedchaos]

With autoImplementAllAPIs enabled, middleware should apply even if the route has not yet been implemented. At this time the middleware is not applied. While such routes do nothing useful, lack of the support can prevent requests from being logged, cors headers being applied (leaving browsers unaware of lack of implementation) and so on.

While it might be convenient even without autoImplementAllAPIs, because of the reliance on express routing without it, implementing it is not viable or really sensible anyway.
