删除消息，撤回消息接口调完之后，再去调用获取历史消息，仍然可以获取到

[627171314]

这两个接口：
jmessage.retractMessage(target: type, serverMessageId: messageId);
jmessage.deleteMessageById(type: type, messageId: messageId);

调用完，再调用获取历史消息接口：
jmessage.getHistoryMessages(type: type, from: from, limit: limit, isDescend: false);
仍然能获取到被删除或被撤回的消息

我这边是撤回消息后 再调用jmessage.getHistoryMessages会因为又Null，导致整个历史消息获取失败。极光这都不咋更新 感觉废了
