Fixes #768

• Updated Makefile to install without errors
• Updated docs to verify whether robotoff is running properly after make dev

@akashtadwai FYI, when you want to propose a feature, you should do it in a specific branch, not in master on your fork. This makes it more difficult for me to test your changes. Also this makes your project master use merge, when it could use fast-forward updates from origin master.

Thanks for the info @alexgarel. Should I create another branch and submit this pull request?

It's ok for this PR, but I really advise you to:

• either remove / recreate your fork (and always work in branches from there on) --> simpler option
• either remove / recreate your master branch on your fork: (I'm not sure 100% of this sequence…)

git checkout -b tmp-branch 
git branch -D master
git fetch upstream
git checkout upstream/master 
git checkout -b master --track origin/master
git push -f
git branch -D tmp-branch
