In sharded cluster, can't read from view whose pipeline has $collStats and is a view on another view

      In a sharded configuration, users cannot query a view if its backing namespace is also a view and its pipeline contains $collStats. More concretely,

      db.createView("firstView", "somethingElse", []);
db.createView("collStatsView", "firstView", [ { $collStats: {} } ]);

      All queries against collStatsView incorrectly fail with "command not supported on view".

      This bug does not affect views that don't have $collStats in their pipelines. It also does not affect views whose pipelines contain $collStats but have a collection as their backing namespace.
