Can't findOne, update, delete on composite primary keys

[matthewmueller]

create table variables (
  name text not null,
  key text not null,
  value text not null,
  email text not null,
  primary key(name, key)
);
insert into variables (name, key, value, email) values ('a', 'b', 'c', 'd');

// typescript error
client.variables.findOne({ where: { variables_name_key_key: { key: 'b', name: 'a' } } })
client.variables.update({ where: { variables_name_key_key: { key: 'b', name: 'a' } } })
client.variables.delete({ where: { variables_name_key_key: { key: 'b', name: 'a' } } })

I can't reproduce this with prisma2@2.0.0-alpha.797, binary version: f608db3b9e4f50f9a384356e532357b0a525969a. Initially when I marked this as a confirmed bug I assumed that @matthewmueller referred to implementation that client will have @@id. Right now no such functionality is exposed via the client.
