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.
