Use base SHA for patches and diffs

This commit changes the revisions used for diffs. The current behaviour is
to show all changes between current tip of master and tip of the MR, rather
than matching the output of the web frontend (which just shows the changes
in the MR). Switching from start_sha to base_sha fixes this.
