[FIX] stock_account: getting value from context in stock valuation layer

Attribute Error: 'frozendict' object has no attribute 'default_product_id'
traceback that occurs in stock/stock_quant: action_inventory_at_date
was caught by a sentry.

steps to produce:-

- Install inventory module
- Select any product from the menu item/reporting/stock
- Click replenish button & from that replenish wizard, select the product again
- Then click the forecasted stat button and in forecast click the On Hand button
- Then click Inventory At Date.

At this moment you find a traceback.

Because default_product_id is not getting from the context in inventory.

Applying these changes will resolve this issue.
