Module seems incompatible with translations

Hi,

I'm trying to implement path based cache invalidation with AWS Cloudfront, and we're facing an issue where when we update the translation of a page, it doesn't seems to be added to the invalidation queue if the original node is there "or vice-versa).

It does make sense since both the tags and the table doesn't seems to take translation into consideration. While this may as well be linked to the core not adding the current language to cache tags, I think we at least should validate if this module really face an issue with translation and see from there how and where we should fix it.
