Refactor predefinedSelections update function

[mdroidian]

from these changes: #146

oldValue wasn't updated to previousValue which is:

      const previousValue = toCellValue({
        value: result[columnKey],
        uid: columnUid?.toString(),
      });

If the selection label was different than data (attribute name), oldValue would return "" and prepend the block with the new value.

eg:
as status select Status
as abc select Status
