File Explorer sends request to user bucket even when accessing group bucket

## Description:

When navigating to the File Explorer in Onyxia and clicking on a non-user bucket (such as a group bucket), Onyxia still sends a request to the user bucket in the background.

## Steps to Reproduce:
- Go to the File Explorer in the Onyxia interface.
- Click on a group bucket or any bucket that is not the user's personal bucket.
- Observe that a request is still made to the user's personal bucket, even though it was not selected.

## Expected Behavior:
No request should be made to the user bucket if the user is interacting with a different bucket (e.g., a group bucket).
