[FIX] point_of_sale: disallow refunds from multiple invoiced orders

Before this commit, users could create a refund order from multiple
invoiced orders. However, such an order could not be invoiced as it was
associated with more than one account_move, leading to a failure. This
commit fixes this issue by preventing users from creating a refund
order from multiple invoiced orders.
