wot-ui 1.14.0 wd-upload组件auto-upload设置false后change事件无法触发的bug

可以临时采用before-choose事件触发下默认的fileList赋值逻辑，否则这个版本是没法同时进行的。

参考如下：

<wd-upload multiple v-model:file-list="fileLists" ref="uploader" :limit="6" show-limit-num :auto-upload="false" :upload-method="handleUpload" :before-remove="beforeRemove" :before-choose="beforeChoose" @change="handleChange" @success="handleSuccess"></wd-upload>

const beforeChoose = ({fileList, resolve}) => { fileLists.value = fileList resolve(true) }
