merge-ort: remove command-line-centric submodule message from merge-ort
There was one case in merge-ort that would call path_msg() multiple
times for the same logical conflict, and it was in order to give advice
about how to resolve a conflict. This advice does not make as much
sense with remerge-diff, or with merge-tree being invoked by a GitHub
GUI for resolution of messages, and is making it hard to provide
which-logical-conflict-affects-which-paths information in a machine
parseable way to a higher level caller of merge-tree. Let's simply
remove this informational message.
