Frontend Pull Request Description

copied changes of shekela:bugfix/NUI-6241-drilldown-empty-values from #719

"Hey, I created function which renders the specific values for undefined or false values. In the case the data contains null, undefined, false and etc. In case of undefined or null data was not rendering values after null or undefined because those values do not have properties, so it was error in console, so I mapped data and when I was rendering the data I turned undefined or null values to string "undefined" or "null" and it continued working. I render string and "-" for false or undefined values. Strings can be changed to specific values whatever will be necessary from function. I run spec.ts file also with additional case and it doesn't break any other code. There are no errors in console."

Since Helpdesk is no longer providing write access to Nova repo for new interns and CircleCI does not recognize PRs from forked repositories, I copied changes from #719 in order for @shekela to merge his PR. Iam not the original author of the source code in this PR it only copies changes by @shekela
