【报Bug】摇树优化会清理掉cli构建的项目中public中的文件

示例代码：

// vue.config.js，如没有此文件则手动创建
module.exports = {
transpileDependencies: ['uview-ui'],
pwa: {
manifestOptions: {
"name": "xxx",
"short_name": "xxx",
"description": "xxx",
"theme_color": "#000000",
"icons": [{
"src": "public/img/icons/icon_x16.png",
"sizes": "16x16",
"type": "image/png"
},
{
"src": "public/img/icons/icon_x32.png",
"sizes": "32x32",
"type": "image/png"
},
{
"src": "public/img/icons/icon_x48.png",
"sizes": "48x48",

},
{

操作步骤：

vue.config.js中配置了以下文件，结果发现引用的图片全被摇树给优化掉

预期结果：

public目录存在引用的图片文件

实际结果：

public没有存在这些引用的图片文件
