Replace the app files atomically and docker stop first before starting up for succeeding commits

[asakapab0i]

In django application, everytime a commit is added and the action triggers the script it loses the link to the original files and I think its because in the script it deletes and replace the app files.

So I added two things to ensure that the refreshed files are properly loaded.

• Replace the app files atomically
• Use docker restart instead of up

Let me know your thoughts.
