Filenames on BC preview page link to nowhere

Created by: danielmarquespt

Clicking on the filenames on the preview batch change page leads the user nowhere. Currently they are just an anchor for the link it self.

Expected behaviour: Link to the actual file in Sourcegraph. If this is not possible the name of the file should be just plain text.
