In the conflict analysis, unnamed nodes look like `OTT: {mrcaottXottY}`

1. The OTT: part seems incorrect? We could just write "unnamed node mrcaottXottY" or something.

2. Less important, but if you click on the link and visit the node in the synth tree, we generate a more useful name like: "[Thermococci + Korarchaeota]"

I'm not sure if the conflict analysis result contains enough info to construct these more-interesting names though. But if it did, we could write something like "Thermococci + Koracheota (mrcaott666ott25307)"

Possibly I could just make otcetera provide more interesting witness names for mctaottXottY nodes.

 "node902033": {
  "status": "conflicts_with",
  "witness": [
   "mrcaott1100ott1732"
  ],
  "witness_name": [
   null
  ]
 },
