 When sanitizing the bridge pool assignments for #2372, I noticed that the
 BridgeDB logs mention some bridge fingerprints more than once with
 changing IP addresses.  Here is an example:

 I didn't find a case when a bridge was added to different rings, but I
 didn't look closely.  I wonder if this affects giving out bridges in some
 way, either by giving out a bridge's old IP address or by giving out a
 bridge more often than others.
