    Revert object-assuming changes to _post_live_migration()
    
    Change I140bfec2a52bf659a725a7dbe78ba5c527ed26de converted the
    _post_live_migration() call to assume it was passed an object
    because the post_live_migration_at_destination() method uses them.
    However, it is also called from live_migration() on the source,
    which clearly is still using instance dicts.
    
    This patch reverts the changes that assume an instance object,
    as well as the tests that were changed as a result. It also
    changes the clear_events_for_instance() call to use dict syntax,
    since that is called from the live migration path currently.
    
    (cherry picked from commit 887d214186631d3d1f49451fa72feb11251d2176)
