On SideBySide diff UI the 'Download' icon of the right version does not work when the left version is not 'Base', get the left version even if clicking on the right icon; 'Download' icon of the left version always gets to be the 'Base' version, even if not comparing with 'Base' at the left side. These bugs can also be found on Unified UI. Fixed. Change-Id: I903d03460d4eff54ab1e92e4025b4414f8d33413
