I've hit a problem with some doctrine listeners, built by decorating an abstract definition.

I want the abstract definition to hold the tag, however because the RegisterEventListenersAndSubscribersPass runs before abstract definitions are removed, they get added as method calls to the EventManager definition, which once the abstract service is removed, we end up with a method call that breaks the container.

I don't know if this is the best approach, it might be better not to return abstract services when calling `findTaggedServiceIds` instead?
