Noel 09cb778b6e clean up SdrObject cloning
using operator= implies that overwriting an SdrObject is a
useful operation, but that is not at all true - they are typically
linked into and referred to by many other things.

So rather use a copy-constructor.

Also clean up a couple of weird "do some stuff after the clone"
code into the main copy constructor.
