Issue with translations api return (undefined index in settings)

[OriginalEXE]

Hi there,

WordPress version: 4.1
Theme active: Twenty Fourteen (irrelevant)
Plugins active: none
Error: Undefined offset: 1 (wp-includes/l10n.php:945)
How to reproduce: Go to wp-admin -> Settings -> General and then check your error report logs

So it seems that an array of languages returned by WP api call has an issue. I inspected and the language in question is "Hazaragi" (haz).

The issue happens when languages are being listed in language selection "dropdown", the actual code is:

esc_attr( $translation['iso'][1] )

but upon inspection, and for this language only, iso is available under key '2' and not '1', not sure why.

I only found this problem today, not sure if I did not notice or something was changed recently in api response. In any case, my tickets search did not result in finding the same report so there you go.
