[FIX] stock_account: set current date for accounting entries

The accounting entries generated (during confirmation of moves on real time
products) were based on the move date. This is correct but the creation of the
entries (from quants_move) is done before the change of state of the move
(which set the date of the move to now).
Instead of using the date of move that is changed a few steps laters, use
directly the current date for account move date.
Fixes #4147, opw 619902
