支付流程工作完全正常，但是当使用慢速测试卡时，无法再次购买消耗品。使用的插件是 in_app_purchase: ^3.0.4。\n要重现该问题：

\n
1. 购买带有“慢速测试卡，几分钟后批准”选项的产品。
\n
2. 一旦启动，然后关闭应用程序。
\n
3. 打开应用程序。购买流将被触发并await InAppPurchase.instance.completePurchase(purchaseDetails);成功运行该购买。\n但此后，当我尝试购买该产品时，Google Play 应用内购买处理程序会抛出错误：您已经拥有该商品。\n整个过程当应用程序在此过程中未关闭时，可以成功运行。
\n

而且我也无法将该产品转换回消耗品。
