Issue:
Changing user story status moves the user story to the Unclassified swimlane
## Description

If I change user story status with Python API, the user story moves to the Unclassified Kanban swimlane. This happens with both https://api.taiga.io and local hosted Taiga.

## Steps to reproduce

The code is like this:
```
from taiga import TaigaAPI

api = TaigaAPI(host=...)
api.auth(username=..., password=...)
project = api.projects.get_by_slug(project_slug)
story = project.get_userstory_by_ref(user_story_key)
story.status = new_status_id
story.update()
```

## Versions

- Python 3.10.12.
- Taiga Python API library: 1.3.0

## Expected behaviour

The status of the user story should change. The story should move in the Kanban swimlane to the new state. The swimlane should not change.

## Actual behaviour

The status of the story does change. This is correct.

But the user story also moves to the Unclassified swimlane. This is incorrect.

## Additional information

If I change the status in Web UI, the user story stays in its swimlane.

I tried to change the user story swimlane:
```
story.swimlane = new_swimlane
story.update()
```

This only works if `new_swimlane=None`, then this moves the story to the Unclassified swimlane.
If `new_swimlane` is an integer id of the swimlane, this doesn't work.
