[AIRFLOW-2204] Fix webserver debug mode
The command `airflow webserver -d` crashes because it tries
to call the method run from the cached_app returned value,
i.e. a DispatcherMiddleware instance. To run the flask app
in debug mode (without gunicorn) it has to be created
directly via create_app, that returns a Flask instance.
