Installer: Fallback to DefaultInstaller on API >= 24 for uninstall,

Browse Source 
... when PackageInstaller is the installer (privext).

* In the case where the Privileged Extension is installed,
  but the installation happens through DefaultInstaller still
  due to something like a permission mismatch,
  that is set as the installer package name.
* We cannot install packages installed by that via the system methods,
  so fallback to DefualtInstaller for uninstalling as well when the
  app is installed by PackageInstaller
