Remove trailing \n from t.Log and t.Error messages as it's unnecessary.
In some instances, combine multiple t.Error()s into one
To provide more consistency across the tests, rename e to err and use %v
as the format arg for errors.
Replace Logf and Errorf with Log and Error when it made sense. For
example t.Errorf("%v", err) to t.Error(err)
The RemoveRRset method was the only one that had a check for RRsets.
While adding multiple identical RRs is an error, there should be now
check for that at this level.
