This patch only ensures that response object is send along with set_language()
call. In later changes, response object can be used by set_language() to set the
language cookie.
Tests:
- Relevant functional tests pass.
- Edit current user's language. The language is immediately set.
- Edit another user's language. The language of the current session is not changed.
