[JS] event.target.matches not working on IE 11

[grandmaster44]

Hi! Thanks for the bundle.

https://github.com/ConnectHolland/cookie-consent-bundle/blob/119ce69e8e7b9435a7c240fdecb2a3017be8ec79/Resources/public/js/cookie_consent.js#L25

https://caniuse.com/#feat=matchesselector As you can see event.target.matches not working on IE 11.

There are two solutions:

1. add msMatchesSelector

   var matches = event.target.matches
               ? event.target.matches('.ch-cookie-consent__btn')
               : event.target.msMatchesSelector('.ch-cookie-consent__btn');

2. addEventListener on cookieConsentForm

   var cookieConsentFormBtn = document.getElementsByClassName('ch-cookie-consent__btn')[0];
   // Submit form via ajax
   cookieConsentFormBtn.addEventListener('click', function () {...});
