Fix TablespaceCreateDbspace() to be able to create a dummy directory in place of a dropped tablespace's symlink. This eliminates the open problem of a PANIC during WAL replay when a replayed action attempts to touch a file in a since-deleted tablespace. It also makes for a significant improvement in the usability of PITR replay.
