Transfer: Hide transfer metadata link if none

refs #7209

Previously, a TransferMetadataSet was created for every Transfer, even
though it was only needed by Disk Image transfer types. It was updated to
only create a TransferMetadataSet (and therefore transfermetadatasetrow)
when needed, which broke rendering the link to the transfer metadata form.
Update to only display the transfer metadata link if it exists.
