fix issues with package.json

when running a dry-run publish, npm complains about these fields:
```
$ npm publish --access public --loglevel verbose --dry-run
...
npm warn publish npm auto-corrected some errors in your package.json when publishing.  Please run "npm pkg fix" to address these errors.
npm warn publish errors corrected:
npm warn publish "bin[fauna]" script name was cleaned
npm warn publish "repository" was changed from a string to an object
npm warn publish "repository.url" was normalized to "git+https://github.com/fauna/fauna-shell.git"
...
```

resolved by running `npm pkg fix`
