fix: add timeout when stopping application

On slower machines, `kill -9` says its stopped the application, but it is still runing on iOS Simulator. For this cases, trying to call `launch` after that leads to error or undefined behavior.
Try to fix this by calling `xcrun simctl terminate` after the kill and add half second timeout.
