    Launch early reachability tests once a minute, not once a second.
    
    This fixes bug 40083, which was introduced in 9f31908a in
    0.2.8.1-alpha.

+  o Minor bugfixes (relay, self-testing):
+    - When starting up as a relay, if we haven't been able to verify that
+      we're reachable, only launch reachability tests at most once a minute.
+      Previously, we had been launching tests up to once a second, which
+      was needlessly noisy. Fixes bug 40083; bugfix on 0.2.8.1-alpha.
