- We upgraded `rugged` to 0.25.1.1 in !10286 for %9.1
- Prior to this upgrade, the default sort order for commits returned by
`Gitlab::Git::Repository#find_commits` was `Rugged::SORT_DATE`, which the
graph relied on.
- While upgrading `rugged`, the MR also changed this default to
`Rugged::SORT_NONE`, which broke commit ordering in the graph.
- This commit adds an option to `Gitlab::Git::Repository#find_commits` to sort
by date, and changes the graph builder `Network::Graph` so it explictly
requests the `:date` sort order
