Fix implementation of NodeOptions::use_global_arguments() (#1176)

`this->node_options_` might still be `nullptr` for a default initialized NodeOptions instance. `use_global_arguments()` must return `this->use_global_arguments_`, in analogy to `NodeOptions::enable_rosout()`. Signed-off-by: Johannes Meyer <johannes@intermodalics.eu>
