Steps to reproduce:

1. Ensure eZ Find is enabled and Solr service is running;
2. Create the following content structure using the admin interface:

Home
	Tests (folder, node_id: 103)
		Article 1 (article)

3. Go to a frontend siteaccess (used main, "eng") and login as a user with sufficient permissions to hide/unhide objects (used an existing admin user);
4. Hide "Tests" folder. There is no hide/unhide button in the toolbar, but it can be done by calling /content/hide/<node_id> in the URL. For reference, used "http://47ezdemo.com/content/hide/103";
5. Run "frequent cronjob" from the installation's root folder:

php runcronjobs.php frequent

6. Search for "Article 1" in either frontend or backend siteaccess, object is found, which is wrong.
