Summary:
The property currentCalls of a CTCallCenter object must always reflect the current situation with phone calls. However, it's no longer being updated if another property of CTCallCenter is set - callEventHandler

Steps to Reproduce:
1. Create an instance of CTCallCenter (single instance to be used throughout the app).
2. Initiate an incoming phone call when the app is running, and log the value of currentCalls property - it will be correct.
3. Hang up the phone call and log currentCalls - it will be correct.
4. Now set callEventHandler property to a non-nil value (some block).
5. Repeat (2) and (3), and after that the currentCalls property will still contain an active call although no call is in progress.

Expected Results:
currentCalls must be updated properly regardless of whether callEventHandler is set or not.

Actual Results:
After the phone call is over, currentCalls is NOT updated if callEventHandler is set.
