Feature/new user snippets breadcrumbs

See merge request gitlab-org/gitlab-ce!21661

**Why?**

The previous behavior had resolved discussions being unresolved
when commented on. This was strange UX, especially since there
is a separate button for "Comment & unresolve discussion".

**Note:**

- Also adds changelog

**Why?**
- These specs had duplicated code for a common context
- New specs for this context needs to be added

**Notes:**
- Also added some `wait_for_requests` to buttons that triggered AJAX
