node tests: Actually test `translations.js`. 

Before this test, we were validating the behavior
of `i18next`, but we weren't validating our light
layer that sits on top of `i18next`, which currently
resides in the slightly misnamed `translations.js`
file.

The translations module is now so small that I'll
just quote it verbatim here:

    import i18next from 'i18next';

    i18next.init({
        lng: 'lang',
        resources: {
            lang: {
                translation: page_params.translation_data,
            },
        },
        nsSeparator: false,
        keySeparator: false,
        interpolation: {
            prefix: "__",
            suffix: "__",
        },
        returnEmptyString: false,  // Empty string is not a valid translation.
    });

    window.i18n = i18next;

We now just do `zrequire('translations')` to initialize
the `i18next` library, which allows us to have simpler
test setup and to actually exercise the above call to
`i18next.init`.

This change now gives us 100% line coverage of `translations.js`,
which of course isn't that hard to acheive (see above).
