Organism endpoint's `has_compendia` always returns `null`

### Context

Was doing some poking at the API trying to figure something out for the cron job tests.

### Problem or idea

```
$ curl -s https://api.refine.bio/v1/organisms/HOMO_SAPIENS/ | jq
{
"name": "HOMO_SAPIENS",
"taxonomy_id": 9606,
"has_compendia": null,
"has_quantfile_compendia": null
}
```
but we definitely have a human compendia.

### Solution or next step

Look at the API view and see what's up. I have a feeling that there is a query issue.

Reproduce the response from the `/v1/organisms/HOMO_SAPIENS/` endpoint and inspect the API view and its query, as suggested in the issue. Trace why `has_compendia` and `has_quantfile_compendia` serialize as `null` despite the reported human compendia. Done means the endpoint returns the correct non-null values for human organisms.
