Sketch 52.1 fails trying to set styles
This code is working properly on **Sketch 51.3**:
```js
import { Rectangle, Shape, Style } from 'sketch/dom';

export default function myCommand() {
  new Shape({
    name: 'sample',
    parent: context.document.currentPage(),
    frame: new Rectangle({ x: 0, y: 0, width: 300, height: 200 }),
    style: {
      fills: [
        {
          color: '#f00',
          fillType: Style.FillType.Color,
        },
      ],
    },
  });
}
```

but it fails on **Sketch 52.1** with:
```js
undefined is not an object (evaluating 't.copy')
```
furthermore removing the style prop like:
```js
import { Rectangle, Shape, Style } from 'sketch/dom';

export default function myCommand() {
  new Shape({
    name: 'sample',
    parent: context.document.currentPage(),
    frame: new Rectangle({ x: 0, y: 0, width: 300, height: 200 }),
  });
}
```
works on both versions.

Is there a new way to apply styles or is the new release API just broken?
