refactor(ivy): fix typo in ngtsc "listLazyRoutes" method (angular#28831)

Fixes a minor typo in the `listLazyRoutes` method for `ngtsc`. Also in
addition fixes that a newly introduced test for `listLazyRoutes` broke the
tests in Windows. It's clear that we still don't run tests against
Windows, but we also made all other tests pass (without CI verification),
and it's not a big deal fixing this while being at it.
