Fix error setting the ID name in disabled alembic nurbs importe

This corrects code that's currently disabled, see `USE_NURBS` define.

The name passed to `BKE_curve_add` was overwritten,
bypassing uniqueness and utf8 encoding checks.

Longer names would cause a buffer overrun as the length of the source
data was passed to `BLI_strncpy` instead of the destination.
