Re: pgAdmin 4 commit: Disable emojis in Yarn output.

Hello Dave,
When running yarn linter after this commit we get the following:

yarn run v1.7.0
$ yarn eslint --emoji false --no-eslintrc -c .eslintrc.js --ext .js --ext .jsx .
$ /Users/pivotal/workspace/pgadmin4/web/node_modules/.bin/eslint --emoji false --no-eslintrc -c .eslintrc.js --ext .js --ext .jsx .
Invalid option '--emoji' - perhaps you meant '--env'?
error Command failed with exit code 1.
