CommentLazyBuilders should be language aware

Problem/Motivation

CommentLazyBuilders always check the default entity language. Even when you view a comment translation you will get links to the default language instead of the translation you are viewing.

Steps to reproduce:

1. Make your comment type translatable
2. Create a comment and then translate it
3. View the comment translation, e.g. visit /fr/comment/1
4. Inspect the local tasks links, you will see that they point to the default language, like /comment/1/edit instead of the translation /fr/comment/1/edit
