KRACOEUS-8198 : Fixes for budget dialogs

The editWithDialog stuff does a deepCopy of the item to be edited. This deepCopy isn't connected to a JPA session so when you click save in the dialog, it tried to lazy load but fails and throws a stack trace. The alternative to removing the lazy loading is to loop through all these items and makes sure this is instantiated. I already do that to some extent for the list items, but it seemed better to just remove the lazy annotation for this one.
