Clicking a stack frame with no source causes all other thread stacks to collapse

[andrewcrawley]

• VSCode Version: master (b2f6194)
• OS Version: Ubuntu 14.04

Steps to Reproduce:

1. Compile https://gist.github.com/edumunoz/6e2ca90d4b5d3dbfa5340576e79ac113 with g++ -g -std=c++11 -pthread hello.cpp -o hello
2. Install the C++ debug adapter
3. Set a breakpoint on line 7 (the body of the test function)
4. When the breakpoint is hit, expand all the threads so you can see their stack frames
5. Click a stack frame that doesn't have source (e.g. clone or create_thread)

At this point, all threads except the one with the frame that was clicked collapse. Clicking a stack frame that has symbols (e.g. main() or test()) doesn't cause any any other threads to collapse.

I would expect that the code view would change to the "Source ... is not available" view without collapsing any of my expanded threads.

Verified that this worked as I'd expect in build 0.10.13-insider.

@aeschli you are on a linux machine, and all this should work out of the box so giving to you to verify.
