Also:
* Refactored some composed components into one inclusive HOC,
called `withUpdateButtonAttributes`.
* The HOC `withTransformSingleSelectToMultipleSelect` allows for the wrong
type to be passed to its wrapped component: if a single element is
passed, that is wrapped into an array.
This didn't play well with TypeScript which obviously complains about
the wrong type being passed to the component.
So we now allow for arrays to be passed as props and ignored by the HOC
