Modifying a section position in a unified document does not apply to content using another language

Steps to reproduce :

• Edit a unified document that has multiple language version
• Move any section to another place in the sections tree
• Save
• Switch to another language

Observed :

• The section is not moved in content, but well-placed in table of content.
• The content is correct after 24h delay

This is caused by the use of a cache macro around the content. The cache id does not update in another language than the default wiki language.

The cache id is built this way :

#set($cacheId = "$!{doc.fullName}-$!{locale}-$!{lastUnifiedDocumentUpdate}-$!{lastSectionUpdate}-$!{xcontext.action}") 

The issue come from the use of tdoc because translated document does not have modification registered in history when Sections objects are modified.

The solution is to add a new key in the cache id string to identify last change in the main document.
