problem and crash
- It turns out we still need the "copyob" still, if for nothing other
than making sure that the unkeyed transforms can get restored. This
was removed originally as I thought that just reevaluating the
animation would work.
- Removed a buggy line of logic that was causing crashes when there
was no animation data. It's better to just assume that if animation
data exists, that something exists there.
- Make Duplicates Real was not clearing data such as the new animation
data or constraints.
