[FIX] account: adapt query for items to reconcile

Changing the bank account on the bank journal led
to a traceback (expected singleton on currency_id)
when trying to open the reconciliation widget.
This is because we are trying to open a blank line
as the origin line was linked to the origin Bank account,
therefore there is no currency_id.

It has been decided to filter the statement line that
match the bank account and to adapt the action button.

Steps to reproduce:

- Create a bank statement line
- In Bank journal, change the Bank Account
- From Accounting Dashboard, click on "Reconcile X items" or
  just open the Bank Journal
-> Traceback (expected singleton)
