mariadb task incorrectly reports state change

[Vladislav Belogrudov]

TASK: [mariadb | Creating haproxy mysql user] ********************************* fatal: [localhost] => Failed to template {{ (haproxy_user.stdout.split('localhost | SUCCESS => ')[1]|from_json).changed }}: an unexpected type error occurred. Error was expected string or buffer

We are missing check here. It should look like

changed_when: "{{ haproxy_user.stdout.find('localhost | SUCCESS => ') != -1 and (haproxy_user.stdout.split('localhost | SUCCESS => ')[1]|from_json).changed }}"
