Can not recumpute cost price in case stock move has not currency

Example stock move:

>>> move = Move(101551)
>>> move.cost_price_required
True
>>> move.unit_price_required
False
>>> move.cost_price
Decimal('0.6300')
>>> move.currency
>>> move.from_location.type
'storage'
>>> move.to_location.type
'production'

When try to recompute cost price, the traceback:

See that stock move, currency is null.
