Clone _cte_alias instead of assigning "self"
Fixed bug in :class:.`CTE` construct along the same lines as that of
:ticket:`4204` where a :class:`.CTE` that was aliased would not copy itself
correctly during a "clone" operation as is frequent within the ORM as well
as when using the :meth:`.ClauseElement.params` method.
