Message: Remove assumption that mapReduce always returns statistics

Starting with MongoDB 4.4, MongoDB will no longer produce execution statistics
for the mapReduce command. The driver no longer assumes that they will be in
the response, and if they are missing will just produce zero values for all
statistics.
