Wrapper invalidation method recursively updates children objects status.

BindingManager::invalidateWrapper checks if the object to be invalidated
carries any children objects and recursively invalidates them.

Shiboken::destroyParentInfo function was refactored to call the new
recursive wrapper invalidator and then call a helper function that
only destroy the parent information.

The invalidate parent test was updated.
