self.__precacheManifest is override

[AidanDai]

when set config like:

{
    importScripts: 'precache-manifest.common.js'
}

write precache-manifest.common.js by https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#full_generatesw_config

importScripts

If one of the imported files sets the self.__precacheManifest variable to an array of ManifestEntrys, those entries will be automatically precached in the generated service worker.

self.__precacheManifest = [
    {
        "revision": "8.0.1",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/normalize/8.0.1/normalize.min.css"
    }, 
    {
        "revision": "4.1.1",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/es6-promise/4.1.1/es6-promise.auto.min.js"
    }, 
    {
        "revision": "0.18.0",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/axios/0.18.0/axios.min.js"
    }, 
    {
        "revision": "2.5.17",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.runtime.min.js"
    }, 
    {
        "revision": "3.0.1",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/vue-router/3.0.1/vue-router.min.js"
    }, 
    {
        "revision": "3.0.1",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/vuex/3.0.1/vuex.min.js"
    }, 
    {
        "revision": "3.26.2",
        "url": "https://cdnjs.cloudflare.com/ajax/libs/raven.js/3.26.2/raven.min.js"
    },
];

I understand that there is no problem, so bug will appear. self.__precacheManifest will be overrideed.

I this two method to resolev this problem, but no one perfect.

I hope you have other better ways to solve this problem.
