TypeError: Property argument of RestElement expected node to be of a type ["LVal"] but instead got undefined

Hey 👋

I wanted to try out your optimize-plugin and ran into the following crash in transform-destructuring
```
errored out during transformation TypeError: .../dashboard.495836a2.js: Property argument of RestElement expected node to be of a type ["LVal"] but instead got undefined

```

The responsible line is [here](https://github.com/developit/babel-preset-modernize/blob/main/src/plugins/transform-destructuring/index.js#L344):
```js
let paramId;
if (isIterable) {
paramId = rest.node.id;
pattern[restOffset || pattern.length] = t.restElement(t.clone(paramId));
} else ...
```

`paramId` is undefined here. The rest object looks like this:

However I don't have any experience with babel plugins and no idea how I could extract more useful information from here.

Unfortunately I cannot share the code, but I can collect more information if you tell me what you need.
