Bump JsRuntimeHost to fix WorkQueue destructor deadlock (#1654)

Bump JsRuntimeHost to include the fix for a race condition in
WorkQueue::~WorkQueue() where cancel() + notify_all() could miss
condition_variable::wait(), causing a deadlock on thread join during
shutdown.

See BabylonJS/JsRuntimeHost#147 for full details and threading diagrams.
