Fix label links for a merge request pointing to issues list

_Originally opened at !2150._

---

I have added a type parameter to the `link_to_label` helper method that is set to `'merge_request'` when in the context of a merge request.

I have also improved the specs to actually test the output of the method instead of its implementation.

Fixes #3007.

You can set type: :merge_request to create a link to merge request
lists instead of issues list. Accept both Symbol & String as type
argument for the link_to_label helper

Puts shortcut key in the right place.

Fixes #13192
