Fix streamer desynchornization caused by streamer debugging patch
it turns out I lost one hunk in the patch disabling extra streaming
which causes streamer to go out of sync in the case non-trivial scc
containing the node being streamed appears in local stream (which seems
quite rare since it does not happen during bootstrap).
