Webhook project setttings fix

[sneakzttv]

The websocket if it's there is already being applied via Web3SettingsEditor.ChainSettings.cs:

if (webHookOptions.Length > 0)
                {
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("Select WebHook");
                    selectedWebHookIndex =
                        Mathf.Clamp(selectedWebHookIndex, 0, window.chainList[selectedChainIndex].rpc.Count - 1);
                    var webhookIndex = window.chainList[selectedChainIndex].rpc.IndexOf(chainConfig.Ws);
                    var selectedWebHook =
                        webhookIndex == -1 ? window.chainList[selectedChainIndex].rpc[selectedWebHookIndex] : chainConfig.Ws;
                    if (GUILayout.Button(selectedWebHook, EditorStyles.popup))
                    {
                        searchProvider = CreateInstance<StringListSearchProvider>();
                        searchProvider.Initialize(webHookOptions,
                            x =>
                            {
                                var str = x.Replace("\u2215", "/");

                                selectedWebHookIndex = window.chainList[selectedChainIndex].rpc.IndexOf(str);
                                chainConfig.Ws = str;
                                changedRpcOrWs = true;
                                UpdateServerMenuInfo();
                            });
                        SearchWindow.Open(
                            new SearchWindowContext(GUIUtility.GUIToScreenPoint(Event.current.mousePosition)),
                            searchProvider);
                    }

                    EditorGUILayout.EndHorizontal();
                    EditorGUILayout.HelpBox("If you set your custom WebHook URI it will override the selection above.", MessageType.Info);
                }

                chainConfig.Ws = EditorGUILayout.TextField("Custom WebHook", chainConfig.Ws);

I've also altered the ternary operator with an extra safety check though just to be sure.

var selectedWebHook = (webhookIndex == -1 || string.IsNullOrEmpty(chainConfig.Ws))  ? window.chainList[selectedChainIndex].rpc[selectedWebHookIndex] : chainConfig.Ws;

No documentation changes are needed.

Looks good, is not breaking existing project settings changes
