Using LocalResponse::into_json in async tests

[bubelov]

Hello again =) Are there any known issues with using into_json in tests? Haven't found any mentions in the doc and GitHub issues. Here are the two approaches I tried:

let req = client.get("/exchange_rates?base=USD&quote=EUR");
let res = req.dispatch().await;
assert_eq!(res.status(), Status::Ok);
let body = res.into_string().await.unwrap();
let body: ExchangeRate = json::from_str(&body).unwrap();
assert_eq!(rate, body);

let req = client.get("/exchange_rates?base=USD&quote=EUR");
let res = req.dispatch().await;
assert_eq!(res.status(), Status::Ok);
// Time to halt forever...
let body = res.into_json::<ExchangeRate>().await.unwrap();
assert_eq!(rate, body);

The first one has more boilerplate, so I tried to use into_json but it halts the test execution (deadlock?). If I switch to sync client then it simply fails with "trying to initialize a runtime inside runtime kind of error. Any ideas?

Here is the full project, calling cargo test simply hangs on this line:

Yes. The issue has been fixed in master for some time and will be in the next release.
