Ctest prints `[object Object]` after return code

[benmcmorran]

Brief Issue Summary

After running a CTest suite, the line [ctest] [object Object] appears in the CMake/Build output pane. Something probably isn't getting deserialized correctly.

1. Create a folder with these files:

CMakeLists.txt

project(ctest_issue)
include(CTest)
add_executable(main main.cpp)

main.cpp

int main() {}

2. Open the folder in VS Code and run the CMake: Configure command.
3. Run the CMake: Run Tests command.
4. Check the content of the CMake/Build output pane.

Additional Information

The problem is here. The vscode.TestMessage is directly logged in ctestFailed(), but it's not a string.

Thanks @benmcmorran, I've confirmed that this isn't a regression. However, I can confirm that this only repros if the cmake.ctest.allowParallelJobs setting is disabled. I've put the bug in to 1.18.
