 But I'm afraid it's a small project to start writing tests for this class
 now, and that shouldn't block the bugfix.

 Hmm, I prefer having a coded proof of the fix.  It doesn't seem such a
 huge task from merely looking at the class.

 Well, I'll add a ticket for writing this test.

 `processRelayServerDescriptor()` did ''not'' contain a line
 `this.updatedNodes.add(fingerprint);` as it was contained in
 `processBridgeServerDescriptor()`.  We only put relay fingerprints into
 that set that we saw in consensuses, and that's how they all got valid
 `first_seen` timestamps.

 Given that you're currently system-testing this fix (by re-importing) ok.
 Ready for merge.
