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.
