解决 GlobalObject.getContext() 为 null 时, 下载任务出错的bug.
目前 3.8.4 版本 构建的 安卓原生app 运行时 偶尔会出现下列错误, 导致程序异常:

java.lang.NullPointerException
Attempt to invoke virtual method 'android.content.SharedPreferences android.content.Context.getSharedPreferences(java.lang.String, int)' on a null object reference.

此 PR 尝试解决该问题.

虽然提到了 3.8.6 , 但是希望 3.8.5 就能解决.
另外 不知道 iOS 版本是否也有类似问题.
如果有 麻烦 cocos官方修复下.
