接收小程序媒体检测回调消息时的消息去重判断逻辑有问题

[fakebody]

简要描述

接收小程序媒体检测回调消息时，进入方法cn.binarywang.wx.miniapp.message.WxMaMessageRouter#isMsgDuplicated判断消息是否重复

private boolean isMsgDuplicated(WxMaMessage wxMessage) {
    StringBuilder messageId = new StringBuilder();
    if (wxMessage.getMsgId() == null) {
      messageId.append(wxMessage.getCreateTime())
        .append("-").append(wxMessage.getFromUser())
        .append("-").append(StringUtils.trimToEmpty(wxMessage.getEvent()));
    } else {
      messageId.append(wxMessage.getMsgId())
        .append("-").append(wxMessage.getCreateTime())
        .append("-").append(wxMessage.getFromUser());
    }
    if (StringUtils.isNotEmpty(wxMessage.getToUser())) {
      messageId.append("-").append(wxMessage.getToUser());
    }
    return this.messageDuplicateChecker.isDuplicate(messageId.toString());
  }

以下是同一个小程序、同一时间发起的2条媒体检测，解密后的回调数据：

{"ToUserName":"xx","FromUserName":"xx","CreateTime":1655747827,"MsgType":"event","Event":"wxa_media_check","isrisky":"0","extra_info_json":"","appid":"xx","trace_id":"db6a6eb16fd1c8afe425b1c76917cc0c","status_code":"0"}
{"ToUserName":"xx","FromUserName":"xx","CreateTime":1655747827,"MsgType":"event","Event":"wxa_media_check","isrisky":"0","extra_info_json":"","appid":"xx","trace_id":"fbef75edb40bd0b95ea0d138ca6d71f8","status_code":"0"}

只有trace_id不同，可见这种情况下根据CreateTime及ToUserName不足以作为唯一条件，导致消息丢失

模块版本情况

• WxJava 模块名: 4.3.0

顺带提一嘴，me.chanjar.weixin.common.api.WxConsts.EventType枚举少了wxa_media_check事件类型
