A general point I want to raise here: This removes the possiblity to override the tour module, by putting it into /modules instead of /core/modules. I'm not sure whether this is still possible at the moment in D8, but it was certainly in previous time.

Overriding the Manager class should still be possible, and if that's possible, then this line can be changed. No?

Sure but do you expect that you can't move drupal modules but you require to alter the manager? What about using basename or __DIR__ or something like that here?

That's a great tip!!
