pm2 pull not working if starter-script not in working dir

What's going wrong?

pm2 pull not working if starter-script and executable file not in the same dirs

How to reproduce this issue?

Dirs and files:
/home/start.json
/home/dir/.git
/home/dir/app.py

TestCaseOne:
cat start.json

{
	"name": "app_name",
	"script": "dir/app.py",
	"exec_interpreter": "python3.6"
}

TestCaseTwo:
cat start.json

{
	"name": "app_name",
	"script": "app.py",
	"cwd": "./dir",
	"exec_interpreter": "python3.6"
}

Let's run:
pm2 start start.json
pm2 pull app_name

TestCaseOne: pull successful
TestCaseTwo: there's no .git

Start by reproducing both pm2 start start.json and pm2 pull app_name cases with the shown /home/start.json, /home/dir/.git, and cwd settings. Compare how pm2 pull resolves the starter script and Git directory; done means the second test case pulls successfully without losing access to .git.
