What changes did you make? (Give an overview)
Closes #622

• Removed the check which was not rendering CEL help icon on edit filter. So the help icon is now visible for both add filter and edit filter.
• Added unit test for same icon to be visible and enabled in both add and edit cases.

Is there anything you'd like reviewers to focus on?
