[692] Hope the nuxt.render method has 'data' parameter

example.vue

<template><div>{{person.name}}</div></template>
<script>
  export default{
    data(){
      return {person: {name: null}}
    },
    asyncData(){
      return axios.get('/user/id')
    }
  }
</script>

The key point is when nuxt.render has data parameter then don't excute the asyncData method, directly assigning the parameter of data to example.vue's data. Like this

  //Koa2 env
  app.get('/user/:id', async ctx=>{
    const data = {person: await mongoose.user.findById(ctx.params.id)}
    //If can't find the person, nuxt render 404 page.
    nuxt.render(req, res, data)
  });

In this case can save a little network request overhead
