I'm adding/editing '''!TranslatableString''', and when I enter two '''!TranslationString'''s with same lang,

 '''IntegrityError at /admin/i18n/translatablestring/1/'''

 columns main_id, lang_id are not unique

But I excepted some suitable error message in red!"		closed	contrib.admin	0.96		duplicate		jshaffer2112@…	Unreviewed	0	0	0	0	0	0
