authors field inconsistent between Works dump and .json endpoint

Here is work `/works/OL15348267W` from the [Open Library data dumps](https://openlibrary.org/developers/dumps):

```json
{
"title": "Living Peace: the open space of our lives. An initial consideration of the personal practice Open Space",
"created": {"type": "/type/datetime", "value": "2010-08-23T21:58:29.243780"},
"last_modified": {"type": "/type/datetime", "value": "2010-08-23T21:58:29.243780"},
"latest_revision": 1,
"key": "/works/OL15348267W",
"authors": [
{"type": {"key": "/type/author_role"}}
],
"type": {"key": "/type/work"},
"revision": 1
}
```

And here it is from https://openlibrary.org/works/OL15348267W.json :
```json
{
"title": "Living Peace: the open space of our lives. An initial consideration of the personal practice Open Space",
"created": {"type": "/type/datetime", "value": "2010-08-23T21:58:29.243780"},
"last_modified": {"type": "/type/datetime", "value": "2010-08-23T21:58:29.243780"},
"latest_revision": 1,
"key": "/works/OL15348267W",
"authors": [

],
"type": {
"key": "/type/work"
},
"revision": 1
}
```

Note the differences in the "authors" field.

Start by comparing the dump representation and https://openlibrary.org/works/OL15348267W.json for work OL15348267W, then trace how each representation is generated. Determine why the authors field differs and verify that both outputs consistently represent the work after the fix.
