Comment(by nickm):

 My working theory is that this happens when a relay is extending to a
 bridge.  The bridge doesn't send an AUTH_CHALLENGE (since it doesn't want
 to be authenticated to).  But that's the trigger for a public relay to
 send a NETINFO cell, so the public relay never sends the netinfo.
