      Post-push fix for BUG#13728026.
      
      After pushing the patch for BUG#13728026, some tests started failing
      on valgrind because the repository was not being registered in the
      Relay_log_info object. So when the thread and the Relay_log_info were
      destroyed the memory allocated for the repository was not freed
      causing a memory leak.
      
      The Relay_log_info object is responsible for destroying the repository.
      
      In this patch, we correctly register the repository in Relay_log_info
      object.
