shell: Avoid advertising applications without app_id set

When using GTK-3 to create apps, the framework issues set_parent_id
which forces a surface to be added even before the app_id is set.
This causes the compositor to try to advertise an invalid app_id.

This patch avoids advertising an app which has no app_id set.
