Fix filtering projects & groups on group pages

Closes #40785

See merge request gitlab-org/gitlab-ce!16584

Wrap Rugged-exceptions in Gitlab::Git::Repository#write_ref

Otherwise we'd only preload the ancestors that would fit the
page. That way, when a search result was on the first page, but the
ancestor didn't fit the page anymore. We would not have the preloaded
ancestor when rendering the hierarchy.

When a project is shared with a group, it should not be included as a
descendant on the group dashboard.

When searching we would limit the scope of ancestors to load because
the filter would be applied to the ancestors. Instead, we need to load
_all_ ancestors for matching projects.
