When pushing updates to an application installed using QtIFW, the entry in the "Installed Apps" still has details pertaining to the previous update.

Method to Reproduce
1. Inspect "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{GUID}
1. Provide an update with a new version or name, using .rcc
2. Update installation using `maintenancetool.exe update --accept-messages --confirm-command`
3. No changes to "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{GUID}

Candidate Fix
In packagemanagercore_p.cpp:1676

        if (m_core->isInstaller() || m_core->isUpdater())
            registerMaintenanceTool();
