Raw revision of cached git repository in search view

[Jun Omae]

If searching changesets in cached git repository, the revisions are displayed with no changes. The issue doesn't occur if mercurial because search system requires revision table and mercurial connector doesn't support cache.

We should show shortened revisions in search view.
