    fdo#66984: Define an assignment operator to prevent double deletion.
    
    The code path was assigning one ScDPObject to another via assignment,
    but we didn't define one. So we were using the compiler generated
    assignment which only shallow-copies data members, which ultimately
    caused double-deletion of one of its data members.
