Fix null returns for Background colors with columns in Twig ~3

I noticed that the background selection for "no background" is not saving correctly. Probably the reason it returns the null warning.

I have fixed the issues for background color returns null . Kindly review the above attached patch file.

Thanks, Edgar for reporting.
Thank you, Shreya, for patching.
Reviewing and testing the fix

I don't see the error anymore but the form view still doesn't show the no background as selected.

Facing two issues under

• 9.1.x-dev ( the colors are showing up with Drupal ~10.1.0 at the back-end )

and

• 10.0.x-dev ( showing at the back-end- but not showing bg colors for columns at the front-end )
