fix rate limit validation in alias handler

[iamorchio88]

In addition to the fix , we have to pass the instance of store . Example: ` module.exports = { name: "api", mixins: [ApiGateway],

settings: { port: process.env.GATEWAY_PORT || 3000,

routes: [
  {
    path: "/test-service",
    rateLimit: {
      window: 10 * 1000,
      limit: 2,
      headers: true,
      key: (req) => req.headers["x-forwarded-for"],
      store: new MemoryStore(), // HERE USE INSTANCE
    },
    whitelist: [
      "test-service.test",
    ],
    bodyParsers: {
      json: { limit: "2MB" },
    },
    aliases: {
      "POST /test": "test-service.testAction",
    },

  },
],

onError(req, res, err) {
  console.error(err);
  res.setHeader("Content-Type", "text/plain");
  res.writeHead(err.code);
  res.end(err.data || err.message);
},

}, methods: {}, }; `

I've checked the code and route.rateLimit is fine. The createRoute method merges the route.opts.rateLimit with the this.settings.rateLimit global config and puts the merged config to route.rateLimit in line 1343, so the route.rateLimit is the final config after merging.
