Time to decode frame message is printed even after the call is terminated

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Make a video call
2. Wait for the message to start show up "Time to decode frame...but some RTP 
packets are missing (missing_seq_num_start=4462, missing_seq_num_count=-45, 
last_seq_num_with_mark=4461). Postpone :("
3. Terminate the call

What is the expected output? What do you see instead?
Those messages should stop being printed. Sometimes it stops sometimes it goes 
on and on without ever stopping regardless if the call is still active or not.

What version of the product are you using? On what operating system?
Branch 2.0 rev 1246 on iOS 8 and 7.
