Make sure the actions and conditions run fine, even with upgraded conditions, actions without settings for the new operations (view own, ..)

Added an upgrade for the removed workflow-ng action 'Set content permissions' - it'll be converted to an 'Grant content permissions by role' action

improved grant optimisations to don't write per node grants for roles, if authenticated users are granted access by content type permission
