PartialResponseError on startup
See https://github.com/home-assistant/core/issues/91703

User can see status in TC app and website, but cannot load data via Home Assistant.

Full log at original ticket above, but basic issue is here:
```txt
  File "/usr/local/lib/python3.10/site-packages/total_connect_client/location.py", line 258, in _update_zone_details
    raise PartialResponseError("no ZoneStatusInfoWithPartitionId", result)
total_connect_client.exceptions.PartialResponseError: ('no ZoneStatusInfoWithPartitionId', OrderedDict([('ResultCode', 0), ('ResultData', 'Success'), ('ZoneStatus', OrderedDict([('Zones', None)]))]))```
```

Maybe our refactoring of code has led to #112 coming back ?

In `location._update_zones()` if we see Zones=None we highlight that with a log message telling the user how to fix it, and then raise TotalConnectError.

But in `location._update_zone_details()` [which only runs once at startup] we don't provide a log message and raise PartialResponseError.

Waiting for the user to verify that a panel sync fixes this.
