Description

When the server rejected an access token the client still considered valid (e.g. clock skew after wake), the token got renewed silently but the folder was never loaded again, so an existing folder showed "Resource not found" until a reload.

• handleAuthError now resolves to whether the token got renewed.
• The folder loader retries the load once after a successful renewal.
• A 401 on the retry goes through the normal auth error handling again (renewal first, logout only if it fails), so a valid session isn't ended, as intended by fix: retry silent token renewal before logout on auth error #2951.
