Setting `false` on a resolver arg in typeConverterResolversOpts doesn't disable it

With the code:

```js
const composeWithMongoose = require('graphql-compose-mongoose').composeWithMongoose
const User = require('../../../models/User')

const opts = {
description: 'A user of the application.',
resolvers: {
findMany: {
filter: false
}
}
}

module.exports = composeWithMongoose(User, opts)
```

...`filter` argument is still available on the `findMany` resolver. This code should disable it, no? Or am I understanding it wrong?
