Start a Wiki test in new Global Nav

If you would return CreateNewWikiPageObjectStep1 object in the previous method you can than verify this page not base on URL but it's content which also might be beneficial.
In order to do that you would need to add this verify method CreateNewWikiPageObjectStep1, and as part of this method you can check if all inputs are visible and url contains Special:CreateNewWiki. With this approach Special:CreateNewWiki url would be strictly related with page object and there would be no need to move it to content file.
