Adapt right side in join if lateral detected

Adapt right side in join if lateral detected

Fixed bug where use of :class:`.Lateral` construct in conjunction with
:meth:`.Query.join` as well as :meth:`.Query.select_entity_from` would not
apply clause adaption to the right side of the join.   "lateral" introduces
the use case of the right side of a join being correlatable.  Previously,
adaptation of this clause wasn't considered.

Fixes: #4334
