Add ActionVersion

[artur-intech]

Deleting a contact with actions should create both contact and action versions (log_contacts and log_actions respectively).

Needed for #1146.

[vohmar]

no records are created in log_actions table on contact update in registrant portal - records are created/updated in action, contacts and log_contacts.

[vohmar]

epp contact:delete returns internal error if contact has records in actions tabel

[vohmar]

internal error is still returned upon an attempt to delete a contact with records in actions table
