Fix all objects getting selected sometimes when droppping object

If no other object was selected while dragging one in (e.g. from the Outliner
or an object asset from the Asset Browser), all visible objects in the active
view layer would get selected.
Issue was caused by a wrong enum type use.

Mistake in bcdba7c34d.
