Fixes list_passband_online_history()

The call to this function expected to receive a dict from the server but it instead received a list. The list is now converted to a dict. It does so by parsing a fixed number of characters to determine a date string, which might be problematic for non-EN locales but I can't think of any robust way to make this work automatically.
