- Root cause: accessing req.get("dataset_ids") returns None when the key
is absent, causing KeyError.
- Fix: use req.get("dataset_ids", []) to default to empty list.

When creating and updating chats, add a check for the parsing status of
knowledge base documents. Ensure that all documents have been parsed
before allowing chat creation to improve user experience and system
stability.

**Main Changes:**

- Add document parsing status check logic in `chat.py`.
- Implement the `is_parsed_done` method in `knowledgebase_service.py`.
- Prevent chat creation when documents are being parsed or parsing has
failed.

### What problem does this PR solve?

The `/api/v1/chats` API endpoint was broken, any GET request got the
following response:
```
{"code":100,"data":null,"message":"TypeError(\"'int' object is not callable\")"}
```

With this log ragflow-server side:

```

``` 
This was caused by the incorrect use of `logging.WARN` as a method (it's
a loglevel object), instead of the correct `logging.warning()` method.

This PR fixes that, and also rewrites the message to be grammaticaly
correct.
