This fixes an issue where we sometimes failed to retrieve the SSID; we
sent one initial request before the family ID had been set.

Then, we received the family ID and tried to send another
request. However, if the first request was still in progress, the
second request was never made.

Since the first request lacked the family ID, that response didn’t
contain anything useful.
