flash-store缓存未被及时删除，导致对比事件异常。

[su-chang]

问题描述：

修改联系人相关信息，收到dirty事件后，没有对比出信息变更的差异，导致无法及时更新联系人的数据。

收到dirty事件后，根据日志分析 PuppetContactMixin 中的缓存均被清理掉（cache MISS），调用 puppet-service 层获取数据时，正常日志为 cache SET 而异常日志为 cache HIT

目前怀疑导致该问题的原因是 puppet-service 删除flash-store中的缓存数据耗时较大，导致wechaty再次请求新的底层数据时，仍获取到的为旧数据。

解决方案

获取新数据时增加小量延迟（100毫秒）

经过测试，可以完美解决该问题，甚至延迟可以减小至50毫秒

将删除缓存的操作前置

由于 onDirty 函数在wechaty-puppet-service@1.0.79中已经改造为异步函数，在触发dirty事件前，await onDirty()即可。
