i18n javascript on login page requires login

[Jouke]

When using the Horizon version currently available on git, Angular is unable to load due to - it appears - the i18n JavaScript file being unable to load.
The request for this JavaScript is being redirected when at the login screen. When logged in, loading this file is giving no problems.

Browser consoles gives the following:
/dashboard/auth/login/?next=/dashboard/i18n/js/horizon%2Bopenstack_dashboard/:5 Uncaught SyntaxError: Unexpected token <

At which point the whole Angular app seems to fail due to not having gettext available.

The redirect to the login page happens consistently on two instances of devstack (both set up this week), both http and https, Chrome 59 and Firefox 54.

The impact of this bug is very small:
- Keystone credential login appears to work as usual
- Federated login/WEBSSO does not hide the user/pass fields, creating an inconvenience of having to fill in useless data for these users. This is how I found out about this issue.

Hi, Jouke.
After this patch(https://review.openstack.org/#/c/490131/) merged, the problem no longer exists. You can pull the latest code.

Hi Wei Ying, you are right, the fields now disappear - thank you for mentioning the patch.

Fix Committed means a fix is merged into the repository. In this case, this patch(https://review.openstack.org/#/c/490131/) is not a fix. The issue just disappears after that, so "Invalid' looks better.
