Revert "Revert "i18n fixes""

Summary:
As translator, any supposed arbitrary coding style which
breaks the translation is not acceptable.
We can certainly discuss the proper long term solution
about fixing the coding style, about fixing QML, about
fixing gettext, or any other fix, but knowingly
breaking the translations is not acceptable.

We can certainly discuss after.

This reverts commit b5fc1a76.

Test Plan: Transltions works.
