CPR display on stream event does not update after editing ascent

[killakalle]

To reproduce:

1. Log an ascent of a 7a route with Lead Redpoint
2. Look at the CPR: 2801
3. Change the ascent to Second Hangdog
4. Look at the CPR in the stream event

Expected:

• CPR is reduced to 2151

Actual:

• CPR on the stream event is still the same: 2801

It looks like the actual CPR of the ascent in the background is adjusted. So, it's probably only a minor issue with the update of the CPR displayed on the stream event
