Move symfony/stopwatch to require instead of require-dev

[ruudk]

It seems that jms_serializer.stopwatch_subscriber has a dependency on stopwatch debug.stopwatch. If symfony/stopwatch is not installed, it will result in:

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: The service "jms_serializer.stopwatch_subscriber" has a dependency on a non-existent service "debug.stopwatch".

When I add symfony/stopwatch to my composer.json it works.

How to solve this?

Having the same problem, I think the solution for this should be in \JMS\SerializerBundle\DependencyInjection\JMSSerializerExtension:

if (!$container->getParameter('kernel.debug') || !class_exists(Stopwatch::class)) {
    $container->removeDefinition('jms_serializer.stopwatch_subscriber');
}

Nice, added a PR to fix it! Thanks for the hint :)
