fix what seems to me like a minor mistake in BreedIdentifierHandler

can't see a reason the new token shouldn't have the same name slot as

cut compile-time dependency of BreedIdentifierHandler on nvm, prim
cut runtime dependency of BreedIdentifierHandler on nvm, prim
relocate BreedIdentifierHandler to parse0

now that its engine dependencies have been cut
fix oops in TestModels
