Update conditions for MySQL removal in destroy role

The conditions to execute the MySQL database and user removal tasks in the Ansible role have been updated. Now, these tasks will run not only when 'mysql.service' is present in ansible_facts.services, but also when 'app_mysql_database' or 'app_mysql_user' are defined. This ensures more robust removal when cleaning apps.
