[wix-users] Bundle Rollback with Major Upgrade of packages

It has to do with how Burn detects MSI packages. This is what it looks like
in v4 right now when installing a bundle with a minor-upgraded package:

Detected related package: {6F171EC9-0774-4974-A8D1-493EF53CAB74}, scope:
PerMachine, version:, language: 1033 operation: MinorUpdate
Detected package: PackageA, state: Present, cached: No, install
registration state: Ignored, cache registration state: Absent
Planned package: PackageA, state: Present, default requested: Present, ba
requested: Present, execute: MinorUpgrade, rollback: None, default cache
strategy: Keep, ba requested strategy: Keep, cache: Yes, uncache: No,
dependency: Register, expected install registration state: Present,
expected cache registration state: Present

I don't think any of this detect or rollback logic has changed between v3
and v4. Because the ProductCode and UpgradeCode are the same for a minor
update, Burn detects the package as Present. Burn won't rollback the
package if it was already installed.

Something to keep in mind is that if the major-upgraded package is not
rolled back then the bundle should stay installed on the machine so that
package can be uninstalled. This would mean that both the old bundle and
the new bundle would be installed at the same time.
