de-optionalize union types to support Optional for m2o

Fixed bug in new ORM typed declarative mappings where we did not include
the ability to use ``Optional[]`` in the type annotation for a many-to-one
relationship, even though this is common.

Fixes: #8668
Change-Id: Idaf0846e49cc12095394b99ad6fe678735cf9242
