[Bug]: Accounts - I'm able to hide the selected Account

### Describe the bug

I'm able to hide the selected Account. Then, this account disappears from the account list, however I still see this account as the selected one.

### Expected behavior

Either we should not be able to hide the current selected account, or if we do, we should then switch the selected account for a non hidden one

Start by reproducing the issue in the Accounts menu with a selected account, then trace the account-list and selected-account UI paths. Verify the behavior when the selected account is hidden, and consider the issue done when the UI either prevents hiding it or selects a visible account afterward.
