Do not change notification timestamp when making it read or unread.

Marking a notification as unread resets the timeago stamp causing
the times to look wrong. It can be reproduced by marking an old
notification as unread. Using the update_column instead of
update_attribute will not touch the updated_at attribute, and
thus will not affect the updated time ago in the view.

Fixes #6798.

closes #6821
