Fix sidebar labels scoped label selection bug
What does this MR do and why?
This MR fixes a sidebar labels scoped label selection bug.
When a scoped label is currently selected in the label dropdown, then if another scoped label from the same set is picked then the currently selected scoped label is sometimes not unselected. This happens because currently the code finds the first scoped label and unchecks it but it doesn't check that it's a selected scoped label. The correct logic is that only one scoped label is ever selected.
