    [IMAPx] Handle gracefully when service is unavailable for get_folder_info()
    
    Return TRUE, as 'success', in case the namespace response is not available,
    which can be for cases like server being reachable, but the service unavailable,
    which allows to return at least the last known folders for the account, like
    in the offline mode.
