Title: Fix: Displays 'on host [object Object]' in log

Given provisioned **pm2-deploy** with multiple hosts like

```js
deploy : {
production : {
user : "ubuntu",
host: [
{
host : "121.201.7.226",
port: "58020"
},
{
host : "192.168.33.80",
port: "22"
}
],
...
```

When deploy to remote, the log cannot show correct host deploying instead of `[object Object]`
```bash
$ pm2 deploy production setup
--> Deploying to production environment
--> on host [object Object]
○ running setup
○ cloning git@github.com:theone-dev/orange.git
```
