indexcontent cronjob, executed in an environment setup with Yoochoose hooked as legacy search fails, with an UnauthorizedException, if there are objects to index for which anonymous user has no read access.

Steps to reproduce

• Install and patch eZPublish 5.4
• Install and configure eZRecommendation Bundle, making sure that legacy support is enabled (see Install procedure notes)
• Enable DelayedIndexing
• Update a user content object (or create a new one)
• Execute indexcontent cronjob

  php ezpublish/console ezpublish:legacy:script --env=prod runcronjobs.php --siteaccess ezdemo_site_admin indexcontent
