Enhance `wc/guard-super-call` with fix 

It should be relatively simple to add a fix for `wc/guard-super-call`

Take a simple error state such as:

```js
connectedCallback() {
  super.connectedCallback();
  this.setAttribute('bar', 'baz');
}
```

and change it to this:

```js
connectedCallback() {
  if (super.connectedCallback) {
    super.connectedCallback();
  }
  this.setAttribute('bar', 'baz');
}
```
