Newnym does not change curcuit
When I check circuits via `getinfo circuit-status` after sending NEWNYM signal it seems that tor doesn't change the circuit at all. Steps to reproduce: 1. Start tor with control port. 2. Connect to control port, authenticate, `setevents signal` 3. Repeat `getinfo circuit-status` and `signal newnym` 4. During that, make no requests through tor. Example log attached. I thought that response 650 indicates that circuit was successfully changed. **Trac**: **Username**: vpdevel
