Merge branch 'pending-delete-project-notifications' into 'master'

Exclude projects pending delete from notifications

Make `NotificationSetting.for_projects` exclude projects that are excluded by the default scope on `Project`. (At the moment, that's projects with `pending_delete: true`.)

See https://gitlab.com/gitlab-com/support-forum/issues/819
