Objects with same name

If a have two objects or InputObject with same `Name`, GraphQL return the error: **Unknown type "String"** or something like this.

Ex: Two objects with name `timeType`

```
var timeInputType = graphql.NewInputObject(graphql.InputObjectConfig{
Name: "timeType",
Fields: graphql.InputObjectConfigFieldMap{
"value": &graphql.InputObjectFieldConfig{
Type: graphql.Int,
},
"time": &graphql.InputObjectFieldConfig{
Type: graphql.Int,
},
},
})
```

```
var timeType = graphql.NewObject(graphql.ObjectConfig{
Name: "timeType",
Fields: graphql.Fields{
"value": &graphql.Field{
Type: graphql.Int,
},
"time": &graphql.Field{
Type: graphql.Int,
},
},
})
```

There is a easy way to debug this error?
