Fixed holosigns not registering it's projector (#61755)

Before the mapload PR got merged, the mapload param got treated incorrectly as the loc param, allowing the proc to work without problems since source_projector is in the right place. But now that the mapload param is implemented here properly, the previous bad implementation turned into a working feature turned back into a bug. This took way longer than it should have.
