Before this commit, there were a crash if you tried to add an optionnal
product in a new sale order without saving it.
Apply same logic as in the ListRenderer: buttons with type="object" are
disabled for no saved yet records, as calling the python method with no
id would make no sense.
To avoid to expose this logic inside all Kanban views, we define a
specific KanbanRecord Class for the One2many case.
This could be refactored to prevent from duplicating this logic in list
and kanban views.
