fix: create simpleResponse in table with a new list

[QRuhier]

• Can't Generate Collected Var with Table and QCU in measured data #868

=> some code had been removed (commented) since the migration to Vite, so we could not add in a table a singleResponse with a new code list
=> even before that, the form was not well initialized (not on "new code list" by default)
