Fixed three failing test cases related to Revit project.

<h3>Fix for Test Cases</h3>
Now there are passing, but i will be adding more verification to them once we fix the issue with Document.IsFamilyDocument.

I have changed version for file MAGN_122_wallsAndFloorsAndLevels.dyn, because it was not migrating correctly.

Logged defect for non migrated nodes. (http://adsk-oss.myjetbrains.com/youtrack/issue/MAGN-3725)
