Set use_mapper_path=True for with_poly subentities
Fixed regression in joined eager loading introduced in 1.3.0b3 via
:ticket:`4468` where the ability to create a joined option across a
:func:`.with_polymorphic` into a polymorphic subclass using
:meth:`.RelationshipProperty.of_type` and then further along regular mapped
relationships would fail as the polymorphic subclass would not add itself
to the load path in a way that could be located by the loader strategy. A
tweak has been made to resolve this scenario.
Fixes: #5082
