Embargo: document under embargo is counted in search result on the site

A document under embargo is counted in search result on the site. There are 3 documents in total of which one is under embargo. So on the site the search result should be 2, but is 3 and an error is logged (see attachment)

Steps to reproduce:

• create 3 documents in the CMS
• put 1 document under embargo
• go to the site and open the events page
• the site shows that 3 documents are found
