UAssetImportTask::bReplaceExisting is not supported with interchange

Add this code to a function you call from a blue utility widget or any other way to start the import with this code.

1. TArray<UAssetImportTask*> ImportTasks; 
2. for (int32 i = 0; i < cFC.Files.Num(); i++)
3. { #   FString& cFile = cFC.Files[i]; #   UAssetImportTask* nTask = NewObject<UAssetImportTask>(); #   nTask->AddToRoot(); #   nTask->Filename = (cFC.SrcPath / cFile); #   nTask->DestinationPath = cFC.DestPath; #   nTask->bAutomated = true; #   nTask->bReplaceExisting = false; //this is being ignored by interchange importer #   nTask->bSave = false; #   #   ImportTasks.Add(nTask); # }
4.  
5. AssetTools.ImportAssetTasks(ImportTasks); //this leads to the interchange stuff...

This is a regression from the legacy texture importer

Import a texture over an existing one with the code provide in the description

The option bReplaceExisting is not supported when using interchange framework.
