fix(go): continue parsing chained selector method calls

[wzekin]

Allow selector traversal to keep visiting chained method calls instead of returning early, so downstream calls can still be collected during Go parsing.

修复：golang 链式调用中，无法正确解析 Function Recv 的问题

(Optional) More detailed description for this PR(en: English/zh: Chinese).

zh(optional):

在下面这样的代码中

type A struct {}
type E struct { A }

func (a *A) AFunction() {}

func (e *E) Return() *E {
    return e
}

func (e *E)  Raw() {
    e.Return().AFunction()
}

AFunction 的 NodeID Name 会被解析成 E.AFunction 而不是 A.AFunction

测试中， Return4 的 MethodCalls 中 DFunction 应该是：

                {
                  "ModPath": "a.b/c",
                  "PkgPath": "a.b/c/pkg/entity",
                  "Name": "MyStructD.DFunction",
                  "File": "pkg/entity/entity.go",
                  "Line": 78,
                  "StartOffset": 1458,
                  "EndOffset": 1465,
                  "Extra": {
                    "IsInvoked": true
                  }
                }

原来的代码中，会返回：

                {
                  "ModPath": "a.b/c",
                  "PkgPath": "a.b/c/pkg/entity",
                  "Name": "MyStruct.DFunction",
                  "File": "pkg/entity/entity.go",
                  "Line": 78,
                  "StartOffset": 1458,
                  "EndOffset": 1465,
                  "Extra": {
                    "IsInvoked": true
                  }
                }

这是干啥

[wzekin]

just test.

[Hoblovski]

可以给 testdata/ 加一个测例吗？期望的行为就是回归测试挂掉，因为你改了 Go parser。

这个去掉吧
