clicks.js needs a check to make sure parent has an ID

On this line:
https://github.com/yireo/Yireo_GoogleTagManager2/blob/master/view/frontend/web/js/product/clicks.js#L11

it'll fail if for some reason the parent doesn't have an ID, this could do with being handled a bit more gracefully otherwise you'll run into errors such as:

undefined is not an object (evaluating '$parent.attr('id').match')

Probably worth just checking $parent.attr('id') exists first.

I will add some additional checks to prevent JS errors. However, if the parent ID does not have an ID and/or if there is no parent with ID starting with product-item-info_ then click tracking will not work. So I guess it is better to investigate why the HTML structure is different and how JS could check - from the perspective of a click-event on a product-link - detect the product ID of that link.

@jissereitsma don't disagree - I'd fully expect click tracking not to work either
