 When a networkstatus consensus download fails, do not wait 60 seconds to decide whether to retry. (Also, log the time at which we'll try to replace the current networkstatus.)

   o Minor bugfixes (v3 directory protocol)
     - Delete unverified-consensus when the real consensus is set.
+    - Consider retrying a consensus networkstatus fetch immediately after one
+      fails: don't wait 60 seconds to notice.
 
   o Minor bugfixes (controller):
     - Don't reset trusted dir server list when we set a configuration option.
