benchmark loading on ios fix (#135)

* fixed build options tweaking in benchmark window

* fixed benchmark mode being stuck on loading screen on ios

CmdArgs() was throwing an exception due to empty argument, and it made it disabled, calling OnDisable, and removing "level loaded" callback, so we were never switching to the game level itself
