* 优化html模板

Some strange bugs occur when the names of the routes are the same.

Documentation: https://panjiachen.github.io/vue-element-admin-site/feature/component/excel.html

复用此组件时因为id不可重复的问题会导致onSuccess指向错误。

Fixed #1125

后台菜单->权限测试页->指令权限 切换角色 会正确 刷新侧边栏

> /src/store/modules/permission.js

原方法在递归筛选侧边菜单后， 会意外修改原始 asyncRouterMap 导致侧边菜单重绘不正常
已经用新方法替代修复  结果入下图
