Union the exclude_properties of the inheriting mapper in declarative
Fixed bug where the "automatic exclude" feature of declarative that
ensures a column local to a single table inheritance subclass does
not appear as an attribute on other derivations of the base would
not take effect for multiple levels of subclassing from the base.
Change-Id: Ibf67b631b4870dd1bd159f7d6085549d299fffe0
Fixes: #3895
