FixupRedirector issues with packages containing multiple public assets (commandlet and FAssetFixUpRedirectors)

A customer is reporting that a renamed LevelSequence will continuously be resaved when Fixing the Redirectors from the Content Browser. The problem would be the incorrect redirector for the BlueprintGeneratedClass ( [Link Removed] To Do ) and the code of FAssetFixUpRedirectors::DeleteRedirectors.

If the ResavePackage commandlet is used instead of the Content Browser, the LevelSequence might get deleted if the package is unreferenced.

Check the code under: Delete unreferenced redirector packages

The name of the package containing the redirector is used to decide if the package should be deleted. It doesn't care if there are non-redirector assets.

See UDN link for reproduction project.
