Active trail for multi-language

Problem:
I created some menu item with different language, and they link to the same node corresponding language.
Then I access the node, other menus (link same node, different language) also active.

Reproduce step:
- Create two menu item with different language.
- EN Example (link. /demo) (not have JP translation)
- JP Example (link. /jp/demo) (not have EN translation)

- Access /jp/demo path.

Solution:

I think we should filter menu link content by current language. I created a patch for this issue.
