      When we run the server with internalQueryFrameworkControl="tryBonsai" some simple queries, such as 

      {$match: {'a.b': null}}

      trigger the optimizer fallback mechanism and produce the classic plan. 

      To reproduce

      buildscripts/resmoke.py run --suite=query_golden_cqf --mongodSetParameters="{internalQueryFrameworkControl: 'tryBonsai'}" jstests/query_golden/null_missing.js
