minor #994 Rebuild assets (bocharsky-bw)

This PR was merged into the master branch.

Discussion
----------

Rebuild assets

Somehow running `yarn build` on TravisCI  sets the repo in a dirty state:
https://travis-ci.org/symfony/demo/builds/541616536

Actually, the same for me when I run `yarn build` locally. I rebuilt the assets - let's check if tests pass now.

P.S. Basically, continue #990 (comment)
