Fixes docker-compose & pg initialization (#10)

* Fixes docker-compose & pg initialization

 - ./scripts/init_db.sh is not executable (/bin/bash: bad interpreter: Permission denied)
 - same script fails because user is already created, only table creation is necessary.

* Actually fix docker-compose development workflow

* Incorporate PR feedback

* Remove credentials.json
