When a page has a translation, the breadcrumbs of the original document and the translation are not the same

Steps to reproduce:

• set the wiki to multilingual with default language to "en" and the supported languages to "en,fr"
• create a page "Main.TestPage1" where the original document (EN) has "Main.WebHome" as parent; next, create a FR translation and leave the parent empty
• create a page "Main.TestPage2" where the original document (EN) has "Main.TestPage1" as parent; next, create a FR translation and leave the parent empty
• create a page "Main.TestPage3" where the original document (EN) has "Main.TestPage2" as parent; next, create a FR translation and leave the parent empty

If you look at the breadcrumb for the EN version of "Main.TestPage3" you see: "Wiki Home" -> "Test1" -> "Test2" -> "Test3" (see "BreadcrumbEn.png") which is correct. However, for the FR translation you only see "Test2" -> "Test3" (see "BreadcrumbFr.png"), so only the Level 1 parent.
