    Fix AnsibleAction.run() when argument is not a dict

    Fix ad hoc commands executed by AnsibleAction.run() when command is not
    passed as a dict() but as a normal string, the same way like ordinary
    ansible command works.
    Check if argument is a dict() and only if it is, use json.dumps() on it.
    And not break commands passed as string.
