New testcases for wgAdDriverWikiIsTop1000 variable

Consider create a new PageObject for Special:WhereIsExtension.
e.g. (other examples in WikiBasePageObject)
 public void openSpecialWatchListPage(String wikiURL) {
		getUrl(wikiURL + URLsContent.specialWatchList);
	}

	public SpecialEditHubPageObject openSpecialEditHub(String wikiURL) {
		getUrl(wikiURL + URLsContent.specialEditHub);
		return new SpecialEditHubPageObject(driver);
	}
