Issue Description

Type: bug report

Describe what happened (or what feature you want)

当我没有在网关添加api分组的时候，一切正常，
当我在网关中添加了api分组，启动网关之后，控制台无法看到网关服务。
When I did not add an API group to the gateway, everything was normal,
When I add an api group to the gateway and start the gateway, the dashboard cannot see the gateway service.

这是我在GatewayConfig中添加的api分组
This is the api group I added in GatewayConfig

    @PostConstruct
    public void doInit() {
        initCustomizedApis();
    }

    private void initCustomizedApis() {
        Set<ApiDefinition> definitions = new HashSet<>();
        ApiDefinition api1 = new ApiDefinition("custom_system")
                .setPredicateItems(new HashSet<ApiPredicateItem>() {{
                    add(new ApiPathPredicateItem().setPattern("/system/sysUser/list"));
                    add(new ApiPathPredicateItem().setPattern("/system/sysOnline/**")
                            .setMatchStrategy(SentinelGatewayConstants.URL_MATCH_STRATEGY_PREFIX));
                }});
        definitions.add(api1);
        GatewayApiDefinitionManager.loadApiDefinitions(definitions);
    }

遇到同样的问题，请问最后是怎么解决的

同样的问题，调用 GatewayApiDefinitionManager.loadApiDefinitions(definitions);后就失效。
且在http://ip:port/actuator/sentinel中，查不到信息。
不调用时，actuator中显示如下：

调用后显示显示如下：
