Set HttpError name to be HttpError

[jesseshieh]

While trying to use error.name, I noticed that the HttpError used by react-admin has its name set to Error instead of HttpError. I believe this is probably due to microsoft/TypeScript#14099

Setting it explicitly seems like it would be fine in this case, but let me know if you prefer a different solution.

Good catch!

The recommendation from https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work is to manually adjust the prototype immediately after any super(...) calls:

class FooError extends Error {
    constructor(m: string) {
        super(m);

+       // Set the prototype explicitly.
+       Object.setPrototypeOf(this, FooError.prototype);
    }

    sayHello() {
        return "hello " + this.message;
    }
}

Could you do that instead?
