Wiki pages are not visible anymore after upgrading from version 3.4.13 to 4.1.4.

If you upgrade Alfresco from version 3.4.13 to version 4.1.4 you will obser that wiki pages with content are nof visible anymore after upgrade. See : screen “empty.jpg” attached. There was something in the page before upgrade, see “before.jpg”. Also see the attached exception when trying to navigate page content after upgrade. See: error.txt

Steps to reproduce:

1) Install Alfresco 3.4.13 out of the box.
2)create a site called "test"
3)create wiki pages page1, page2, page3, page4 with some content.
4) insure content is there and visible like in the screen shot «before.jpg »
4)Upgrade to 4.1.4
 
Observed result: content of wiki pages is not visible when going to "wiki page list" and clicking on a specific page.
None of my pages content are visible.
 
Expected: page be present with content visible.

Hints:
The problem seems to happen when the field “title” is null in “versionhistory”. See test added line 31 in page.get.json.ftl. By adding the test the problem disappears. The root cause of the problem could be that the field “title” is not properly migrated by the patch “AVMToADMRemoteStorePatch”
