echarts 中的关系图，如果将link的source和target设置一致时，无法可见。

Version

4.2.1

Steps to reproduce

1. 打开demo：https://www.echartsjs.com/examples/editor.html?c=graph-simple
2. 修改其中的第一条link， 将source和target均设置为同一个
3. 观察渲染后的新图，原link消失，但是指向自己的link没有出现

What is expected?

会有一条线，指向结点自己

What is actually happening?

不存在该线
