    tests: Make test assertion clearer
    
    If the elements in the resultset differ from what we expect here,
    we just print an unhelpful:
    
      AssertionError: 2 != 1
    
    But it doesn't tell which file is there that should not be. Assert
    on the array contents, so that we get nicer diff prints when the
    result does not match.
