[Bug] Restoring system apps fails when app is not a system app on the current ROM

Guidelines

• I have read the FAQ and it doesn't cover the issue.
• I have searched the issue tracker for open and closed issues that are similar to the feature request I want to file, without success.
• I'm on the latest version.
• I'm not using a test build (alpha/beta/release-candidate).
• This issue contains only one bug.

Describe the bug

• Find an app that is installed as a system app on Phone A, but is not installed as a system app on Phone B
• Backup the app on Phone A
• Transfer the backup to Phone B and restore

Even if only attempting to restore the APK you get this error: RestoreAppAction$PackageManagerDataIncompleteException: PackageManager returned invalid data paths after 300 seconds trying to retrieve them. App data has not been restored

If you don't have two different phones, as an alternative way to reproduce the bug, you can attempt to edit the .properties file in the backup to change "isSystem": true

Expected Behavior

App should restore as a user app on Phone B, despite being a system app on Phone A
