`flasharray_client.get_arrays_space` items are somestimes missing the `parity` value and `id` contains a bad value

[b1-luettje]

This one does not occur all the time and might therefore be tricky to reproduce. At (seemingly) random times the response items do not include the parity value and it seems that in the same case the id value is wrong as well:
