Remove caching of Repository#has_visible_content?

This MR removes the caching of `Repository#has_visible_content?`. The cache for this method is no longer necessary and this should solve the problem described in https://gitlab.com/gitlab-org/gitlab-ce/issues/25278.

A simpler implementation of finding a merge request

## What does this MR do?

This cleans up some code in the issues API as discussed in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/7180#note_19501743

The helper method `merge_request_for_resolving_discussions` was no longer needed as it was only used once. That made it possible to simplify the implementation.
