Upgrade with UpgradeBehavior: uninstallPrevious ignores newly added installer types on existing installs

Brief description of your issue

When a package originally installed with one installer type (e.g., Inno) is updated to include a new installer type (e.g., portable/zip) and UpgradeBehavior: uninstallPrevious is set, winget upgrade will uninstall and then re-install the same original installer type—ignoring both the new entry and the manifest’s installer ordering. Fresh installs of the updated manifest correctly pick the new installer, but existing installations do not.

Steps to reproduce

1. Initial Install
   Create a manifest containing only the Inno installer and install it.
2. Update Manifest
   Update the manifest, add the portable (zip → nested portable) installer first, and set UpgradeBehavior: uninstallPrevious at the top-level.
3. Upgrade
   Upgrade the installed package using the new manifest.

Expected behavior

With UpgradeBehavior: uninstallPrevious, the originally installed Inno package is uninstalled and then the newly defined portable installer (zip → nested portable) is selected (per manifest order or user preference) and installed.

Actual behavior

• winget upgrade uninstalls the Inno-based package and re-installs the same Inno installer.
• The new portable installer entry is ignored for existing installs, despite appearing first in the manifest and despite setting UpgradeBehavior: uninstallPrevious

Start by reproducing the upgrade flow with an initial Inno-only manifest, then an updated manifest placing the portable installer first and setting UpgradeBehavior: uninstallPrevious. Trace the existing-install upgrade path and verify that done means the old Inno package is removed and the newly ordered portable installer is selected for installation.
