Cancel polymorphic loading in optimized get
Since optimized_get for inheriting mappers writes a simple
SELECT, we need to cancel out any with_polymorphic selectables
that interfere with simple column lookup. While adaptation is
another option, just removing the with_polymorphic is much
simpler. The issue is not noticeable unless the ResultProxy
is not allowing "key fallback" column lookups, which will
be the case when this behavior is deprecated.
Fixes: #4718
