Environment: Android 9, EMUI 9.1.0.222 Island 3.7.5

Symptom: Installed Island and enabled God Mode following the tutorial. After that, using share function from any app, invoking the app picker, will make the whole app crash.

Similar to https://github.com/oasisfeng/island/issues/29#issuecomment-507965054 , seems to be recoverable by completely removing the work profile.

Full crash log by adb logcat -v 'color' '*:W'

Captured during clicking share button in Chrome. crash-chrome.log
from Lynket crash-lynket.log
from Pushbullet crash-pushbullet.log

Some apps with custom implementation of that app picker (e.g. Share Weibo) or sharing to specific app (like Share to Wechat in some apps) is not affected.

补充复现：

用下面的代码片段创建一个空的share intent，并通过PackageManagerService查询能够接受分享的包列表。

        final Intent intent = new Intent(Intent.ACTION_SEND);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.setType("plain/text");

        final PackageManager pm = getPackageManager();
        final List<ResolveInfo> matches = pm.queryIntentActivities(intent, 0);

matches 列表末尾会包含一个无法解析的ResolveInfo，所有字段都是null，但 targetUserId 为10（壶中界的id）。

由于EMUI的应用选择框（com.huawei.android.internal.app.HwChooserActivity）也没有处理这个取值为null的异常，所以在Island外触发分享就会导致分享界面崩溃，但壶中界里面没有这个问题。

个人猜测可能是EMUI处理多用户的分享可能有问题，但我对安卓不太熟（上面的code snippet都是谷歌搜的 😅 ），请问这个算是Island引入的Bug还是垃圾EMUI？
