await ctx.render 404

await dev(context.req, {
      end: (content) => {
        context.body = content;
      },
      setHeader: context.set.bind(context),
      locals: context.state
    }, next);

shared.handleRequest(filename, processRequest, req);

webpack-dev-middleware is not return Promise, koa.use middleware, koa next await is broken.
