[ClassCollectionLoader] fixed comment striping on classes in global namespace

Comments aren't striped when the class is in the global namespace, this adds a fake namespace to let the fixNamespaceDeclaration method handling the formating, so we can remove a method.

I've also put dev as minimum policy in composer, otherwise I couldn't install dependencies.
