* Suppression de « (Two-factor auth) »

Change la valeur de la chaîne « two_factor_authentication » de « Identification à deux facteurs (Two-factor auth) » à « Identification à deux facteurs ».
La traduction anglaise entre parathentèse était redondante et gênait la lecture.

Change the value of the "two_factor_authentication" from "Identification à deux facteurs (Two-factor auth)" to "Identification à deux facteurs".
The English translation in brackets was superflous and was getting in the way of the reader.

* Remplace « ' » par « ’ »

Retire de la traduction les apostrophes droites « ' » (U+0027) au profit des apostrophes typographiques « ’ » (U+2019).
En typographie française, les apostrophes typographiques sont utilisées à la place des apostrophes droites. La traduction était jusqu’ici incohérente et utilisait les deux.

Remove from the translation all the vertical apostrophes (U+0027) in favor of the curly ones (U+2019).
In French typography, typographic apostrophes are used instead of vertical ones. The translation was incoherent and used both.

* Remplace « ... » par « … »

Remplace les séries de trois points par le caractère dédié « … » (U+2026).

Replace all the series of three dots by the dedicated character "…" (U+2026).

Replace "A" by "À" when the wrong word is used.

* Ajout d’espaces insécables

Ajoute des espaces insécables suivant les régles nécessaires en typographie française.

Add non-breaking spaces following rules of French typography.

Harmonise la traduction en remplaçant « certain » par sa forme épicène.

Harmonize the translation by replacing "certain" (sure) by its epicene form.

* Corrige un angliscisme

Remplace « adresse e-mail » par « adresse électronique ».

The old implementation sets default From address in mailers. It sets
the address from SMTP_FROM_ADDRESS, or notifications@localhost. The
behavior is occasionally undesired results.

In production environment, notifications@localhost is likely to be
incorrect.
In testing environment, the email address should not be varied by a
environment variable.

After appling this change,

In production environment, it will throw an exception when launching
Mastodon.
In testing environment, the address will be fixed with
notifications@localhost.

* Fix test

Webpack seems to fail to import `react-intl/locale-data/*.js` if those
files has been proceed by babel, and this also breaks applying our translation.

Note that this won't be a problem on English locale, because react-intl
includes it as default and works fine without manually added locale-data.
Also this issue seems to only occurs on production build, but I'm not sure
about reason.
