uni-app 调试时render-whole有效打包后render-whole无效

示例代码：


```html
<view class="list-container" [@touchmove](/user/touchmove).stop [@touch](/user/touch).stop>  
    <list @loadmore="scrolltolower" @scroll="scrollList" enableBackToTop scrollWithAnimation :showScrollbar="false"  
        class="list" v-if="dataList.length > 0" v-bind="customProps" :style="{height:height+'px'}" render-whole>  

        <!--解决无法下刷新bug  -->  
<!--        <cell><text></text></cell> -->  
        <cell ref="top">  
            <view class="topEmpty" :style="'height:' + topEmptyHeight"></view>  
        </cell>  
        <cell v-for="(item, index) in dataList" :key="keyName?item[keyName]:index">  
            <slot :item="item" :index="index"></slot>  
        </cell>  
        <!--    <cell>  
            <view class="load-tips">  
                <text class="end-text" v-if="dataList.length >= total">- - END - -</text>  
                <text class="loading-tips-text" v-else>加载中...</text>  
            </view>  
        </cell> -->  
        <cell ref="bottom" v-if="bottomEmptyHeight > 0">  
            <view :style="'height:' + bottomEmptyHeight"></view>  
        </cell>  

    </list>  
    <u-empty mode="search" :text="emptyText" icon="http://cdn.uviewui.com/uview/empty/search.png" width="320"  
        height="320" textSize="28" v-if="!dataList.length && isLoaded"></u-empty>  
    <u-back-top ref="u-back-top" :scroll-top="scrollTop" :top="showBackTopOffset" @click="topClick($event)"  
        customStyle="opacity: 0.7"></u-back-top>  
</view>

操作步骤：

• 百分百复现

预期结果：

• 整体渲染

实际结果：

• 逐个渲染

bug描述：

• list 和 cell 配合使用，使用 render-whole 整体渲染，调试时真机、模拟器都有效。打包成安装包后无效，还是逐个渲染
