Cascade of errors in Main if quit gracefully while Overlay app still running

[bradgrantham-lunarg]

ENTER in hello_xr console (exit gracefully) on Samsung Odyssey / WinMR results in:

Appears to be a destroy of a child session 0x0 which errors from the Overlay Layer and then from core_validation, then a subsequent invalid swapchain destroy results in an MSVCRT assertion because... a Mutex is being held?
Possibly the same issue as #13

The output in this issue contains the output for issue #13, but also has other issues. Re-run and store new debug output?
