Subject: [PATCH] Check for project deletion when refreshing/deleting
 project_service.

When reading or deleting the google_project_service resource, first
retrieve the project. If it's not found, or if it's pending deletion,
remove the service, as it's functionally disabled.

Also, add a test to confirm the behaviour.

This should resolve #1292.
