Fix Alembic point cloud streaming.

Point clouds are not imported and read anymore. This was caused by an
API change in rB128eb6cbe928e58dfee1c64f340fd8d663134c26 which was not
applied to `AbcPointsReader`. It did not cause a compile error as the
base class as a default implementation for this method.
