📚 Description

Added check to prevent calling .push({}) more then once on window.adsbygoogle object. Described error in the linked issue is happening only when for some reason push method is called more than once.

P.S. I'm not really familiar with Vue.js/Nuxt and for this reason unit test is not included in the PR. This fixed the problem for me in my NextJS project and I decided to contribute. I hope this fix the issue for you guys too.
