[nativescript-ui-listview] Only first item is displayed on iOS

Reproduce:

Create a demo project using the official template
ns create my-master-detail-ng-demo --template @nativescript/template-master-detail-ng

Do not need to change anything, leave the project as it is.

Run it on iOS ns debug ios

Observe that only one car is displayed but the list seems to have the correct height and is able to scroll. However, when the device orientation changes, the list renders correctly and when the device changes back to its original orientation, the list still renders correctly.

The screen recording is too big to upload here, please refer to this video:

Screenshots:

However, running it on Android has no such issue.

使用官方的 @nativescript/template-master-detail-ng 模板重现该问题，然后运行 ns debug ios，并将初始渲染与方向更改时的行为进行比较。调查 nativescript-ui-listview 的 iOS 路径；完成的标准是所有列表项在首次启动时都能正确渲染，而不需要更改方向，同时 Android 不受影响。
