[express]: RequestHandler's 3rd argument fix (#11288)

Browse Source 
* [express]: RequestHandler's 3rd argument fix

It is hot optional. Btw, express instance itself is a
request handler, which can be invoked without 3rd argument,
so, as for now it has call signature with only 2 arguments:
request and response.

Fixes #11164

* Move 2-args call signature to Application interface
