BaseUpdateView title uses the object and not the BD model instance

[diegobeckdorf]

When the model str method uses attributes that might be updated but fail on validations the update template breadcrumbs and title will show the object to_str using the user input that failed.
The BaseUpdateView context title should be loaded using the DB saved instance or the object before assigning the form input attributes

Probably a self.object.refresh_from_db() fixes the issue.
