On "Add duplicate object" the softbody baking info wasn't freed.

Note: currently the 'baking' stores the entire animation system, which
makes further animation refining (or duplicating) useless for a Baked
SoftBody. You can even delete the entire anim system.
This can be presented as a feature too (saves slow armature stuff).
However, I might check on a 'relative' bake too.
