Occasionally `jbrowse get-config` outputs `_id` and `__v` keys:

```
gitpod /workspace/apollo3-annotation/jbrowse_data (create_script) $ apollo jbrowse get-config
{
  "configuration": {
    "theme": {
      "palette": {
....
  },
  "_id": {},
  "__v": 0
}
```

Which result in:

```
 apollo jbrowse set-config config.json
    Error: Failed to add JBrowse configuration — 422 Unprocessable Entity ({"message":"ValidationError: _id: Cast to ObjectId failed for value \"{}\" (type Object) at path \"_id\" because of
    \"BSONTypeError\"","error":"Unprocessable Entity","statusCode":422})
```
