Title: Fix Bug 860869, format last crash date by locale

@lauraxt r? There is no reliable way to get the user's actual chosen locale and, calling toLocaleDateString on the Date object without specifying any locales seems to have no effect (possibly for the same above reason).

Therefore I decided to use the locale stored in the FHR payload and failing that (or there being no support for the locale), just fallback to en-US.
