[FIX] account: Cash registers

In Accounting > Bank and Cash > Cash Registers, when clicking in "More" button
on 'Put Money In' or 'Take Money out', the date used for the bank statement line
created must be the date of the bank stattement(same behaviour then when clicking
on "Add item" in edit mode). It's forbidden to put/take money in/out for a bank
statement which is not open.
