🐛 Unknown file name fallback for link text (#1330)

- File URI’s not showing up when they are in a dependency (unable to
handle konveyor-jdt scheme)
- This is a temporary workaround allowing the violation to still be
viewed when there is no available file name. Need more info to be able
to pull the file name from another place within the dependency.
