A lot of "Super-admin user was successfully blocked. Username and password were updated." in the logs

Problem/Motivation

Every cron run of cache flush generates "Super-admin user was successfully blocked. Username and password were updated." entry in the log. Seems like some check does not work correctly and updates super-admin user every time check is executed.

Steps to reproduce

1. Install the module
2. Flush cache. You'll see one entry in the log "Super-admin user was successfully blocked. Username and password were updated." which is correct
3. Flush cache again. You'll see a new log entry with the same message, but it should appear there, because the super-admin was already secured.
