The original MR [1] fixed red specs for Rails 5.
But while the failed specs were fixed, that changes brought new failed
specs which weren't caught up in [1].

This commit just fixes the fix. :)

New errors are like these:

```

Resolve "Web IDE "Commit" button should indicate when there's a subsequent step"

Closes #48133

See merge request gitlab-org/gitlab-ce!20030

Since we are only using `.po` files for translation we can shave off
some setup time.

Generating the `mo` files also regenerates the PO-files, including
fuzzy translations. Those cause a lot of bugs, and we don't need them
anymore since the `po` files are generated by an external translation service.
