Renamed `parser` test names to mirror `graphql-js` tests - Pros  - Easier to check that `graphql-go` tests are up-to-date with `graphql-js`'s tests - Cons  - Non-idiomatic  - Won't be able to run tests using patterns like `TestParser*`. But not a big deal    Since tests sits within `parser` package.
