When a script in "simulation/helpers/" contained an error. Files in
"simulation/components" aren't loaded. The return value of
`LoadDefaultScripts` indicated an error but was ignored. The simulation
still tried to start.
Now instead of returning a ignoreable error code the error is thrown. In
the common path the error is implicitly rethrown to the JS-function
which tried to start the game.
