BUG: 387041
For Debian packages, PackageKit manufactures the `updateText` and `updates` fields from the package's changelog. PackageKit gives us the `updateText` and `updates` fields, but also includes the original text used to synthesize them in a field called `changeLog`.
So we should only display `updateText` and `updates`, since `changeLog` is just the the raw information used to synthesize them, and if we show it too, there's duplicate information.
