Fix IllegalStateException if repository not found

Deep links to files within a deleted or moved repository threw
IllegalStateException due to ViewFilter.parseRevision accessing an
unset ATTRIBUTE_REPOSITORY.  This was caused by c709c4cbcf passing
through missing repositories to support host index prefix matching.

Check for the missing repository case and return null to force the
ViewFilter to respond with 404.
