rm31701: PO: CSV Supplier Upload shows error "The collab-update-version of message ... is not matching the DB version" in case of KITs

rm31701 (Redmine)

To reproduce the issue:

• Import
• Download CSV
• Change CSV
  • Ask Holger which fields should be changed
• Upload changed CSV

• To POCollabEngineEJB was added code, that checks collab version.

• Idea from Holger & Burkhard:
  • Do not throw exception in IPOImportCSV.checkCollabUpdateVersion() on if ( poData.getCollabUpdateVersion() != poData.getCollabUpdateVersionOrg() ) but add to it && isKitComponent() (or something like this).
