Fix new curve objects showing as UNKNOWN in the outliner

The fix is to unify with the name we had for the old Curves objects.

That means that we will see them bothi (old and new curves) in the outliner
(under two different categories but with different names).

This is considered to be a temporary solution until we remove the old
curve system entirely.
