When Rails is configured with `config.i18n.fallbacks = true`[0] the behaviour of `I18n.exists?` is unclear[1]. It returns true when passed `nil` because fallbacks are considered. This could be fixed by specifying `fallback: false` as a keyword arg to `I18n.exists?`[2] but if we have no key there's no point in proceeding to the check stage.

Issue: #365

exists?check would fallback fromfr-CAtofr.Now, similar to how
I18n.thas the option to disable fallbacks, we can do the following if we don't want to fallback:Screenshots:
