      Description

      We shouldn't ever send queries to shards where the collection does not exist - this can introduce version issues (since version 0 is "special") and cause problems when dropping shards (since the dropped shards are also targeted until refreshed).

      Proposing backport of f93918db (partial or full) - we previously didn't backport b/c potentially a bit dangerous, but has not caused any problems in master for several months, so it's probably burned-in enough.
