The tests down in vtkExportConfigurationTester was Test_vtkAddBeforeSaveHandlerInDEVWorkbook_validWorkbook
Because the BeforeSave Handler tries to create the vtkReferences sheet in an unmodifiable workbook just before save.
- A workaround is to force the sheet creation in the AddBeforeSaveHandler utility.
- use yhe new vtkActivateReferences utility for configuration recreation
- update TestGetAllReferencesFromNewWorkbook test of vtkConfigurationManager11Tester (VBAToolKit_DEV instead of VBAToolKit)

Test KO :
- vtkRecreateConfigurationTester
Update RecreateConfiguration for references management:
- add a addReferencesToWorkbook method to vtkConfiguration class
- update vtkRecreateConfiguration utility (from vtkImportExportUtilities) to use this new method
- add a vtkReferences sheet to the TestProjectForRecreateConf_DEV Excel Template
