Fix paths to FTL files from cron job l10n loading

I moved the l10n loading from /src/emails/getEmailL10n.node.ts to
/src/app/functions/l10n/cronjobs.ts in
c681102, and in doing so, missed
that I also had to update the paths to the FTL files. These are
loaded at runtime, so I didn't get a build error for that either.
