Fix wrapped view function comparison

Browse source 
Wrapped functions are not comparable, see
https://bugs.python.org/issue3564, therefore a marker is used to note
when the function has been sync wrapped to allow comparison with the
wrapped function instead.

This ensures that multiple route decorators work without raising
exceptions i.e.,

    @app.route("/")
    @app.route("/a")
    async def index():
        ...

works.
