Newly created VTL shows all media as FOREIGN as nvremovemedia does not delete all media entries (4043803)

Following disk failure, a VTL has been removed from NetVault as follows:

- VTL removed from Manage Devices

- VTL entries removed from NV/config/diskdevices.cfg

- All of its associated media deleted from the NVDB using CLI tool 'nvremovemedia'

- VTL folder deleted from disk

After successful removal the VTL is recreated using the same device name and media barcode prefix.

However, once added to NV all media shows as FOREIGN, suggesting there are still entries for the old media in the NVDB despite removal.
