Description

PHPUnit 11 checks for any leftovers in error handlers sebastianbergmann/phpunit#5619

How to reproduce

Run FrameworkBundle->boot() in phpunit test.

It results in Test code or tested code did not remove its own exception handlers thrown by phpunit.

Possible Solution

Introduce FrameworkBundle::shutdown() that would cleanup error handler set in boot(). IMO it's reasonable to have some cleanup in shutdown() of things initiated in boot().
