Update for i18n file
The message [[MediaWiki:Formindexmismatchtext]] is missing in the extension. The message is used on the page with the heading in [[MediaWiki:Formindexmismatch]]. I think the current content in [[MediaWiki:Formindexmismatch]] is a bit long for a heading, so it was probably intended as the text for [[MediaWiki:Formindexmismatchtext]].
The attached patch renames [[MediaWiki:Formindexmismatch]] to [[MediaWiki:Formindexmismatchtext]] in all languages, and adds new message content in English for [[MediaWiki:Formindexmismatch]] in the language file.
