Fixed issue# 766
added empty check in notebook visibility for issue #766 for PR#854

Am not able to reproduce it at my local but you are correct we should kee the empty check. But wondering its already done while setting.
I have put the fix at the source rcloud.is.notebook.visible itself so that other calling faunctions also don't get impacted. I didn't put the isTrue check again as it will always satisfy the condition after defaulting. Please review and let me know if this is fine.
removed array for storing the lang info using var instead
