Use sort when verifying contents of outcome collections

Description of Drivers Ticket:

Because the server doesn't guarantee that documents returned by a find call will be in inserted order, spec test runners should be updated to do one of the following when verifying the contents of a collection:

1. Compare the find results against the data in the spec test with no ordering assumptions
2. Use a sort of _id:1 when doing the find
   See DRIVERS-1196 for updated details.
