Update references to annotation2 and hopannotation2

[stephen-soltesz]

This change updates the passthrough views for annotation2 and hopannotation2 name changes.

While this change removes the old names, they will remain in production until we manually remove them. This is a feature for preserving access to the older tables until we decide to decommission them.
