resolves#28201
This PR fixes the navigation issue related to `router.go` that was
identified in issue #28201. After working on this issue I realised that
@xxllxhdj has already created a PR for this in #29847. While their fix
is great, I have added tests to replicate the issue, reused existing
code and `undefined` will be returned in unexpected situations - which
matches the existing functionality.
## What is the current behavior?
If a user navigates from `/home` -> `/pageA` -> `/pageB` -> `/pageC` ->
back to `/pageB` -> then `router.go(-2)` is called the URL will be
updated to `/home` correctly, but the app will try to render `/pageA`.
This happens for any delta < -1.
## What is the new behavior?
The app will correctly render `/pageA`, which matches the URL.
## Does this introduce a breaking change?
- [ ] Yes
- [X] No
