Cannot edit config file by jcli when lcak of vim

[LinuxSuRen]

In some environments, there's novim. But in most cases, vi exists. So we should support both vim and vi.

Here is the error information when executing jcli under a non-vi env:

# jcli config gen
2020/02/17 11:57:46 No config file found.

~~Hello, I've just installed and even though I have vim installed, it still gives this error~~ It was the version, ubuntu snap version is still 0.0.28, installed manually to 0.0.38 and it worked
