Subject: [PATCH] ApiTemplateData: Use strict check for $langCode

This is assigned as boolean false or any string value.
The previous code used in implicit boolean cast to differentiate,
but the check is insufficient given that "" and "0" would also
cast to false. It is not the responsibility of this code to filter
those out.
