    Fix assert for relay/bridge state change
    
    When we added support for separate client tls certs on bridges in
    a2bb0bfdd5 we forgot to correctly initialize this when changing
    from relay to bridge or vice versa while Tor is running. Fix that
    by always initializing keys when the state changes.
    
    Fixes bug 2433.

+  o Major bugfixes:
+    - Don't assert when changing from bridge to relay or vice versa with a controller.
+      The assert happened because we didn't properly initialize our keys in this case.
+      Bugfix on 0.2.2.18, fixes bug 2433. Issue first discovered by bastik.
