Make docker-compose restart works as expected

[husseljoo]

Update the command to create the database only if it does not already exist. This can be achieved by checking the existence of the database before attempting to create it.

currently db:create fails on restart.
change will be allong those lines.
if ! bundle exec rails db:version > /dev/null 2>&1; then bundle exec rails db:create; fi && bundle exec rails db:migrate
