[TIMOB-27767] iOS: Parity: httpClient should trigger error callback when url is invalid

When httpClient is initiated with an invalid URL it currently fails silently. Instead, the behavior should be the same as on Android (call the error callback) Currently, a workaround is to check the URL property is set to null after calling send *Expected Result* Instead, on iOS, error callback should be triggered the same way it is triggered on Android when an invalid URL is provided. *Test Code*

const url = "https://www.google .com/";
// above url have space after keyword google
const client = Ti.Network.createHTTPClient({
    onload: function(e) {
        console.log("success");
    },

    onerror: function(e) {
        console.error(e.error);
    },
});
client.open("GET", url);
client.send();
