/loglike: Express multiple tokens differently from single multi-word value

[arildm]

The /loglike response doesn't distinguish a multi-word value from multiple tokens. Compare these calls:

"han"+verb vs. "hon"+verb by sense: Space in string separates tokens

{ "loglike": {
  "hon..1:-1.000 vara..1:-1.000": 2375.04,
  "han..1:-1.000 vara..1:-1.000": -1774.16,
  "hon..1:-1.000 skola..4:-1.000": 1062.87,
  // ...

"frihet" vs. "jämlikhet" by party: Space in string does not separate tokens

{ "loglike": {
  "Feministiskt initiativ": 78.12,
  "V\u00e4nsterpartiet": 74.7,
  "Moderaterna": -73.75,
  // ...
