    Description

      This test

      var t = db.count_test;
      t.drop();
      assert.eq(0, t.find().count());
      

      will fail if run as

      resmoke.py --suites causally_consistent_jscore_passthrough test.js 
      

      when

      shard_options:
            voting_secondaries: false
      

      This happens because the https://github.com/mongodb/mongo/blob/r3.7.5/buildscripts/resmokelib/testing/fixtures/replicaset.py#L214 does not wait for sharding initialization to be completed.
      Now it waits for isMaster command to return. Instead it should wait for getShardVersion command to return.

      The error usually manifests as the following output in a log:
