On https://nextdev.tiki.org/Development (u: next, p: next) there is weird Error: "Alias HomePage link already present in 5496:27 page(s)"
The duplicate alias error check was checking tiki object relations but not filtering the relation itself. Thus, HomePage, for example, was included in a tracker item field and ending up with 2 relations:
Code incorrectly showed this as alias error. I added a filter to check only for alias types of relations, so we show the error only when 2 pages alias the same and not when a page is included in another page or different entity.
