[FIX] point_of_sale: session's cash journal entries correctly computed

Journal entries related to a POS session without cash are wrong

Steps to reproduce:

2. Go to Point of Sale -> Configuration -> Point of Sale and create a new one
3. Remove the payment method 'Cash' for this POS and save
4. Open a session in this POS, sell something and then close and post journal entries
5. Open the Journal Items related to the session

Solution:
Fix the account_move_line query to match the statement_id with the session's statement_ids
