[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 範本重現此問題，然後執行 ns debug ios，並比較初始轉譯與變更方向時的行為。調查 nativescript-ui-listview 的 iOS 路徑；完成的標準是所有清單項目在首次啟動時都能正確轉譯，而不需要變更方向，同時 Android 不受影響。
