Fixes routing issues

Fixes #17548

Description

This fixes two issues with routing

1. If multiple domains was assigned with the same culture (V15 - Multiple hostnames per culture per node causes backoffice crash #17548) it exploded when showing the urls in backoffice
2. If you have multiple roots (and HideTopLevelNodeFromPath = true), then only children of the first root respected the HideTopLevelNodeFromPath.

Tests

1. Assign multiple domains with the same culture to one item, and ensure it can still list urls.
2. Setup multiple roots and have children of each with the same name. - Verify only the top one is routable (like in v13)

• Also just be creative in weird cases - all test is welcome :)

With the following setup

• DomainOne having the /d-one/ hostname assigned
• DomainTwo having the /d-two/ hostname assigned
• "HideTopLevelNodeFromPath": false configured

The following discrepancies between v13.5.2 and v15(this PR) are found

• Root
  • V13: /
  • V15: /root
• Root => child
  • V13: /child
  • V15: /root/child
• Other => Child
  • V13: This document is published but its URL would collide with content /Root/Child (id=1058)
  • V15: /other/child
