Remove callback for setting bridges as running

changes/bug24490

@@ -1,5 +1,5 @@
   o Minor bugfixes (bridge authority):
-    - We set bridges as running in a callback which runs every 5 minutes.
+    - We set bridges as running when we dump the bridge status to a file.
       Previously, we set bridges as running in a GETINFO controller, but
       these shouldn't modify vital data structures. Fixes bug 24490;
       bugfix on 0.2.0.13-alpha. Patch by Neel Chauhan
