Having more than one `<Defs />` tag in an `<Svg />` doesn't work

**Describe the bug**

When rendering `` elements in `react-pdf`, if you have more than one `` component, only the children of the first one will be applied.

**To Reproduce**

```
const Test = () => (





);

ReactPDF.render();
```

If you remove the first `` component, the gradient in the circle will start to work. In HTML, this SVG works as expected.

**Expected behavior**

You should be able to reference the `id` of any `` inside the ``, not just the first one.
