Title: Upgrade dashboard history view

try(:abstract_model) did never work. try is not required here, lazymodel will safely return nil if abstract_model didnt exist ...
AFAIK t.message is never equal to either 'delete' or 'new', so remove this condition and always show t.messsage.
user i18n model name as label if object has been destroyed mean while.
