Mike Bayer 2702eeffb9 Adjust natural path to relationship's base mapper for aliased class also

Fixed regression in loader options introduced in 1.3.0b3 via 🎫`4468`
where the ability to create a loader option using
:meth:`.PropComparator.of_type` targeting an aliased entity that is an
inheriting subclass of the entity which the preceding relationship refers
to would fail to produce a matching path.   See also 🎫`5082` fixed
in this same release which involves a similar kind of issue.

Fixes: #5107
Change-Id: I5c6717b925060c3f8da42190d1f00d05248befd8
(cherry picked from commit c9bf876d93b9389d6d3b619565f6da166bab5ec2)
