  Remove statefulness from package extras

* This is part of getting rid of vdm.
* We don't need to store state in PackageExtra any more because you can view the history via activity stream, since it now stores the full package_dict #3972. (The package_extra_revision table will be used to migrate old versions of the package to activity_streams migrate_package_activity.py. But from this version of CKAN, we do not need to record PackageExtra.stateit any more.)
* The mapping between PackageExtra and Package is now a simply dict i.e. attribute_mapped_collection - not a vdm StatefulDict any more.
* vdm's OurAssociationProxy is replaced by the vanilla sqlalchemy association_proxy - I'm not clear why we had to prevent scalars being assigned in the first place since it is a dict mapping, not a scalar mapping. Seems ok.
* package_extras_save() now deletes PackageExtra objects, instead of changing state to 'deleted'.
* package_no_state/extras_list is no longer needed because it was only used by package_extras_save()
* migration deletes extras of state='deleted', otherwise they'd suddenly appear
