Make v0 and v1 ControllerController.get_or_spawn have compatible signatures (#1621)

Summary:
Pull Request resolved: #1621

The v0 and v1 ControllerController.get_or_spawn endpoints need to have matching
signatures. v1 added a "self_ref" for the actor mesh. v0 doesn't need it but can easily get it and
not use it.
