[FIX]: remove wrong column_invisibility domain in purchase order list view

Currently, when we add many2many field relation with purchase.order in view
where view does not have state field, it throws error, it is because
purchase.order list view has attrs for column_invisible which parent.state
which is wrong, purchase.order will not have parent.

With this commit, remove wrongly added column_invisible attrs on invoice_status
field.
