Zoekt indices without zoekt_repositories stuck in initializing

Summary

zoekt_indices which don't have any zoekt_repositories gets stuck in the initializing state. The task mark_indices_as_ready that is supposed to move these indices to ready can not move these indices to ready because the scope used in this task with_all_repositories_ready is moving only those indices to ready which have all zoekt_repositories. It is skipping the indices that don't have any zoekt_repositories
