Unexpected results for nested field alias if field arguments used

### What happened?

Using a query like:

```
items {
photos {
thumbnail: url(width:200)
wide: url(width:1000)
}
}
```

Reports success, but the `wide` alias is of a width of `200`, so the second field alias with arguments just returns whatever the arguments were to the first field alias.

### What did you expect?

Either a 422 or some other error indicating that using alias with field arguments is not supported OR gqlgen calls the resolver for each alias with field arguments.

### Minimal graphql.schema and models to reproduce

```
type Item {
photos: [Photo]
}

type Photo {
url: String!
}

query items(): [Item!]
```
