#8640: Fixing consistency between different Enumeration Field flavors…

…' data storage (#8789) * Reworking EnumerationField's logic to store/retrieve its (selected) values * Fixing exception when creating new item with CheckboxList flavor, adding more nullchecks and compactness * Code styling in EnumerationFieldDriver * Code styling in EnumerationField editor template * Fixing that EnumerationFieldDriver and the EnumerationField editor template should read SelectedValues instead of Values directly --------- Co-authored-by: Matteo Piovanelli <[email protected]>
