Interlanguage lists can contain language codes that are redirects
in language data of ULS.
For example, sr is a redirect to sr-cyrl.
So, if sr is passes as one of the language to ULS, its region, script
grouping is failing and the end result will be missing them in the ULS
language list. This should be properly fixed in jquery.uls library.
Tracked at https://github.com/wikimedia/jquery.uls/issues/207
In this patch we are following a simple approach of passing the language
codes to ULS as redirect resolved.
