[BUG] Tenancy should be automatically switched to user's default tenant when the user does not have access to the tenant read from a cookie

[DarshitChanpura]

What is the bug?
The tenant doesn't switch to default Private when logging in as a different user who doesn't have permission to the tenant.

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Launch opensearch-dashboards.
2. Login as admin and create a new user.
3. Switch to global tenant on admin user.
4. Log out as admin and log-in as the new user.
5. Click on Switch tenant from user information menu and see error

What is the expected behavior?
Tenant should switch to a default when currently logged in user doesn't have permission to the tenant stored in the cookie.

Do you have any screenshots?
