When restoring kiosk app after crash, skip app installation steps. Installed apps should already be restored as part of starting crash recovery session.

During crash recovery, StartupAppLauncher::Delegate always reports
network as ready, so it cannot be determined whether the network is
truly available - if it's not update checks will take ~30 minutes
to fail, during which there will be no UI shown (as there is no login
UI in this case).

Additionally, it would be unexpected for the app to recover to updated
version after a Chroem crash.
