[FIX] account_reconciliation_widget: Don't link counterpart to the statement line

Steps to reproduce the problem:

- Issue an invoice.
- Add a bank statement for paying such invoice.
- Reconcile the statement with the invoice. It gets paid.
- Revert reconciliation from the statement.
- Go again to reconcile the statement line.

Expected behavior: The invoice is available to be reconciled again.

Current behavior: The invoice is not available.

That's because the move line of the AR/AP account was linked to the
statement line in the reconciliation process through the field
`statement_line_id`. That field is used for linking the generated
move lines to the generating statement line, not for other things.

This is probably a bad migration from v13 original code to v14, where
the reconciliation and the datamodel changed.

It includes a migration script that mitigates a bit the problem on
past reconciled invoices, removing such link. It doesn't cover other
AR/AP lines, but at least we keep data consistent for these ones.
