fix: apack lose parents-child props, issues#553

[bugkiwi]

修复这个问题：https://github.com/baidu/san/issues/553

因为 apack 生成于编译阶段（基于 ast）， 所以只处理了当前组件的 template to apack，而在 apack 转成 aNode 时候，缺失了父组件传给子组件的数据，比如 class，style；

错误使用 aNodeUtils.pack入参；

因为aNodeUtils.parseTemplate与 aNodeUtils.parseComponentTemplate区别在 parseComponentTemplate 会『自动抽取第一个子元素作为组件根元素』，相应的 pack 也需要调整。
