Revert "Regenerate po and js files"
Generating the translation files (rake gettext:pack) while having fuzzy translations (translations that gettext tried to guess) in the gitlab.edit.po somehow breaks the {lang}/gitlab.po files so git treats them as binary files instead.
You can see this in 9157c300, the es and de translations are no longer diffable.
This also means that the binary files generated here, have overwritten the translation files that were already on master instead of merging them.
This means that the Spanish translation from https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/11183 have dissapeared
Generally using gettext:pack is not really required if you aren't updating any translations. When you do update translations, you should only check in the files you worked on. I'll update the docs to mention that.
