WillBeRemoved, Ensure Travis is OK on PHP 8.1

It only fix one last error due to Doctrine throwing warning on PHP 8.1.
other/tasksTest, 1 subtests trying to load Doctrine_Manager.

To avoid this warning on your setup:
- Use temporary: php.ini error_reporting = E_ALL & ~E_DEPRECATED
- Use temporary: Tybaze/doctrine1, branch compat_php8.1
- Use FriendsOfSymfony1/doctrine1 once merged PR-85
