This commit is in relation to Jira CB-4602. Code was updated in CDVGlobalization.m so that in the getPreferredLanguage method it will return a language tag that is formatted the same as other devices, such as Android.  Currently the method can return a simple tag, such as en for English, es for Spanish, etc.  In order to provide a standard user experience across devices the code was changed so this method will return ??-??, depending on if a simple language tag is selected in Settings and it appeneds the current Locale to the end of the string. If a not simple language tag is selected, like Portugese (Brazil), nothing is done as IOS will already print a string in the format ??-??
