Bug 32356: Install installer translated files on update

If the installer files exist for a given language, the translate script
won't update it.
We should get a confirmation from Bernardo (author of bug 24262), but I
don't understand why it could be needed (side-effects?)

Test plan:
Installer several times the same language, drop the DB and run the
installer+onboarding process.
Check files installed by the installer (yaml for notice templates,
biblio frameworks) have inserted the data properly in DB.
