[FIX] account: auto-reconcile hidden lines

- Create 11 invoices with the same partner but different totals like:
1.0, 2.0, 3.0 ... 11.0
- Confirm them
- Create a bank statement with 11 lines having each of them the previous
invoice amount (1.0, 2.0, 3.0 .... 11.0) and the partner
- Click on the 'Reconcile' button
- In the reconcile form, do NOT push the 'Load More' button, but push
the 'Automatic Reconciliation' button

All lines are reconciled, but a JS traceback is raised.

This is because we try to destroy a widgets which were not rendered.
