* EOAccess/EORelationship.m ([EORelationship

-foreignKeyInDestination]): use destinationEntity to search for pk.

* EOAccess/EODatabaseContext.m ([EODatabaseContext
-_buildPrimaryKeyGeneratorListForEditingContext:]): check if the
relationship propagates the pk to an entity pk.
([EODatabaseContext -relayAttributesInRelationship:sourceObject:
destinationObject:]): record updates for relationship with fk and the
ones that propatates pk.
