[FIX] account_reconcile_widget: analytic tags formatting

before this commit. analytic tags are not correctly formatted when sent to
the server after reconciliation, that lead to an error being raised.

Steps to reproduce the problem:

- Create a reconciliation model of type "Manually create a write-off on clicked button".
- Show analytic on the configuration and show the optional column "Analytic tags".
- Put any analytic tag.

When using such reconciliation model on the reconciliation, the analytic tag
is not well formatted and you can't complete the reconciliation.
