Query: copy-paste error in the SelectExpression Equals method, could lead to null refs/other errors

SelectExpression -> private bool Equals(SelectExpression selectExpression)

code:

            if (!(Having == null && selectExpression.Having == null
                || Having != null && Predicate.Equals(selectExpression.Having)))
            {
                return false;
            }

should be:

            if (!(Having == null && selectExpression.Having == null
                || Having != null && Having.Equals(selectExpression.Having)))
            {
                return false;
            }

Should use Equals(Having, selectExpression.Having) as @AndriySvyryd suggested at some point.
