If you run install composer install --classmap-authoritative then running phpunit fails with the error Class "\Symfony\Bridge\PhpUnit\SymfonyTestsListener" does not exist.

The cause seems to be that the class is now just an alias and not a concrete class (see symfony/phpunit-bridge@48139af#diff-7f2565259188dda68869a0605b70c219L33) so composer cannot add this to the class map.

I am nut using simple-phpunit but a the phpunit defined in my composer require-dev because i wish to use johnkary/phpunit-speedtrap.
