Describe the issue you are experiencing

After configuring a button with the Assist action and assistant (pipeline) set to 'Preferred assistant', it opens the last used assistant instead of the preferred assistant.

Describe the behavior you expected

'Preferred assistant' should always use my preferred assistant, even if it's different from the last used assistant.

Steps to reproduce the issue

1. Have two assistants/pipelines, example: A (preferred) and B.
2. Use assistant B, close the Assist dialog.
3. Create a button card with Assist action, assistant (pipeline) set to 'Preferred assistant'.
4. Click on the button.

Result: assistant B is used.

Expected result: assistant A is used.
