typos on validator test queries

[chris-ramon]

Related to: #71, some queries are not matching the ones from graphql-js

• TestValidate_UniqueOperationNames_FragmentAndOperationNamedTheSame

Current

query Foo {
  field
}

mutation Bar {
  field
}

Should be

query Foo {
  ...Foo
}
fragment Foo on Type {
  field
}

• TestValidate_ArgValuesOfCorrectType_ValidInputObjectValue_PartialObject_IncludingRequired.

Current

{
  complicatedArgs {
    complexArgField(complexArg: { requiredField: false })
  }
}

Should be

{
  complicatedArgs {
    complexArgField(complexArg: { requiredField: true, intField: 4 })
  }
}
