Add a way to check what params was instance initialised with

It would be good if we could check what params was each instance initialised with. Similar to `toHaveBeenCalledWith`

For example:
```
const createPolygon = () =>
new google.maps.Polygon({
strokeWidth: 1
});

it('constructed polygon', () => {
createPolygon();
const polygonMocks = mockInstances.get(Polygon);

expect(polygonMocks[0]).toHaveBeenCalledWith(expect.objectContaining({strokeWidth: 1}))
});
```

Probably not working example, but just to get the idea. After reading the code I believe there is no way of doing this at the moment?
