CollectionView does not relay out its cell when rotating device

### Problem description

The snippet below shows incorrect layout after the device has been rotated. There is to much space allocated to the cells which now fit into two lines, were they required three lines before. The cells are not properly relayouted.

### Expected behavior

The layout should be consistent after rotating the device.

### Environment

- Tabris.js version: 3.0.0-beta2
- Device: iPhone 6
- OS: iOS 12

### Code snippet

```jsx
import {CollectionView, Composite, contentView, TextView} from 'tabris';

contentView.append(
{
return

;
}}
/>
);
```
